Lighting Remains Underwater
When you place a Torch underwater, it gets destroyed quickly by the surrounding water, yet the light that it emits still remains. The same occurs for Jack-o-Lanterns after destroying them, but not Redstone Torches. I do believe it occurs with Lava as well because I noticed some Obsidian at the bottom of the ocean that was lit-up in a chunk I've never entered before. Only tested this in SP. --Dessalet 12:03, 10 October 2011 (UTC)

Water World (Never Ending Water)
I've traveled over 300 blocks (currently at 150, 340 ish) and my world is still nothing but water. There were a few (like four of five) small islands anywhere from six to ten blocks across with no resources on them except for two reed plants near where I spawned in. No trees or anything else. Possible Biome generation bug.

- Edit. Finally found some land. Still nothing but small-ish islands but at least there are a few trees. Had to travel all the way to X: 550 Z: 620 before I saw them. Still no large land masses.

Seed: 1391535874094239712

-confirmed in my seed too. I traveled 17,000 blocks before I reached land again.

- I found a tree 2-3 chunks in one direction from spawn, you could see it.. -.- And when i reached it i saw more land full of trees..

- Didn't notch or someone else talked about deeper oceans?
 * More interestingly, when I entered this seed, I spawned on dirt in survival mode. That must be another error, I think. --Lulloman 09:19, 26 September 2011 (UTC)

game not pausing
when you are non-fullscreen and tab to another window the game pauses. If you open the smelting screen then tab to another program, the game continues to run.58.96.55.124 08:39, 10 September 2011 (UTC)

^^^^ This has always been the case. If you open your inventory screen, a chest, the workbench, a forge, ect... the game will continue to run when you alt tab. It only pauses if you have nothing opened.

Workbench duplication
I don't know if it works in Multiplayer, and I don't know if it is just in Windows XP. But if I place something on the workbench and then press F11 to close fullscreen, and then return to fullscreen (by again pressing F11) the workbench window closes, leaving the object duplicated on the ground. However, it is not possible to pick up stashable items without "converting" them first.

To do this you must aim at the edge of the workbench when opening it, this will make one of the duplicated items to fall down from the bench and the other one still placed on top of it. When you open the workbench and place, say a block of diamond inside, then pressing F11 to close fullscreen and then press again to get it in fullscreen mode again. Now use the sneak/crawl command to move close and only picking up one of the items. Place this block in the workbench and divide it to nine. Then you can do the same to the other block and you have two.

If you simply pick up to things they will get placed in the same square and therefore the duplication will be destroyed. Duplication of none stashable items such as food or buckets will not be destroyed. Aaah, this reminds me of the old days of Diablo 1.

I have been searching for other reports of this bug but haven't found any, if this is already reported, please remove this one. I hope someone fixes this bug because it realy is disturbing and I can't stop doing it.

- confirmed for me also in win7 64bit 58.96.55.124 08:24, 10 September 2011 (UTC)

Redstone Repeater Partial Glitch
I have noticed that when breaking a Redstone Repeater it shows the pumpkin particles Can someone confirm???

^I've noticed this as-well.^

^^Erm, that's been there forever...^^

^^What Version on you on? lol^^

Door bug
If you jump the place where a door will open, and then open it, you are able to get on top of the door. This allows you to jump two blocks up instead of one. Aneesh 18:39, 30 April 2011 (UTC)

mobs spawning by your bed in well lit areas
if you use our bed in a well lit area mobs can spawn near your bed. this is a known bug. what i learned is what causes the bug. if you plant your door from outside you house so the door is closer to the outside of your house mobs can come in to your house and wake you up. if you do it the other way mobs dont attack you at night. this also depends on you door placement. one of my houses has a cactus farm an mobs cant get to the door so mobs can wake me up. so it seems that the close doors planted from outside your house basically just work like open doors for mobs. this bug i simple to come across an annoying as hell.
 * Maybe, but it's also known bug afaik.. I took a glance at the Bed list in the main page to see if it was there but that list is a mess in general - good example

If you try sleeping in a bed on SMP server while standing on it This from the single player list, of course Lalophobia 11:48, 3 May 2011 (UTC)

^^^

This has been a bug for a long time now. It has to do with two factors, in most cases it is the placement of your door. If you are doing double doors you will (almost) always get this glitch. Also, if you place your door while standing outside your house you will get this glitch. It has to do with the hinge of the door and mincraft thinking that the door is open when in fact it is closed.

I would think you would know this, but if your bed is up against a 1 thick wall, monsters can get you.

SMP Snowballs
Thrown Snowballs hitting passive mobs (like pigs or sheeps) will knock them back without doing any damage. But if you throw them at other players, they will go straight through them without any effect. When Snowballs are fired from an dispenser, they'll have no effect on other players or yourself. They will go straight through you. If PVP is off, this is intentional. Assisstion 12:14, 8 October 2011 (UTC)

SMP Drowning
If you are drowning, your armor will get damage and loose duration, too.
 * Not a glitch, occurs in SSP as well. Armor acts as damage reduction (and takes duration damage) from all forms of injury. Somehow this includes drowning. Darkid 12:14, 2 May 2011 (UTC)
 * Doesn't really make sense, does it? I think it still counts, so I'll list it as an omission. LTK 70 13:21, 3 May 2011 (UTC)
 * Of course armor won't help in real life, so Minecraft would be a little more realistic if they added this. But basically this isn't a bug.

If you are drowning, you will get knocked back with every bit of damage you take, making it impossible to reach the surface.

Possible SMP Mob Spawning Bug?
This is something I and a few friends have noticed on our server, but I wanted to check and make sure it wasn't a Bukkit-specific thing. It seems like certain mobs will never despawn like most, constantly building up until there are ridiculous numbers of them. We've so far noticed this with Ghasts, Squids, and Slimes. Doesn't seem to happen with anything else. The Ghasts were so bad we had to actually disable them as the Nether became one giant white cloud that rained fireballs on all who entered :)

Anyways, like I said, we run Bukkit so I didn't want to add this without confirming it was a universal thing. --Warlock 20:40, 2 May 2011 (UTC)


 * An easy way to check is to disable all mods, re-enable them individually and see if it has any effect. Of course, that means no more Nether, but you could still check on the numbers of other mobs. I personally haven't noticed a lack of despawning mobs, although slimes can often be problematic in large strip mines. LTK 70 13:12, 3 May 2011 (UTC)
 * It's not my server so not really an option :( --Warlock 16:00, 3 May 2011 (UTC)
 * This bug existed in Minecraft Beta 1.4. Slimes and squids wasn't despawning. Even after hundredthousand of mobs spawned I saw some squids with an ID of 50 and so and the same happened with slimes. After some time were wasn't even more monsters spawning in these chunks maybe because they were full. But I don't know if this happens in 1.5 too because I haven't found any old squids and there are a lot monsters spawning at any time. --Sworddragon 16:38, 3 May 2011 (UTC)

reformatting ?
Is it an idea to reformat this page (using I.E.: a template to get some additional attributes to each bug..Which hopefully will help Mojang solve it quicker in the long run.. and easier to read and digest the page for everyone) - SNIPPED CLICK FOR REST

This reply in proper context here
 * I'm just a little worried this is going to get absolutely huge. I mean, there are a LOT of bugs on the list.  Also I wonder if priority/impact should be included - I'm just thinking of the crazy edit wars that might take place because different people have different perceptions of bug priority.  Also not sure what the @Jeb box is for, considering I don't believe Jeb is even working on MineCraft right now.  Notch is the one fixing these.


 * Otherwise I think this isn't a bad idea. It will probably be a lot of work to convert though.


 * P.S. - I absolutely agree with distinguishing if a bug is in both SSP and SMP - current layout doesn't really take this into account (you can kind of assume SSP bugs also occur in SMP, but that may not always be true)--Warlock 15:14, 4 May 2011 (UTC)


 * [[Known_bugs/formattest#This_is_what_I_replied | I think I made some edits while you were typing that

-SNIPPED CLICK FOR REST- quite a wad of text ]]


 * OK I've gone ahead and 1. I cut this huuuge entry out this page ((~at least my part, I didn't feel like I should have moved someone else's reply as well)) ..anyway 2. Also I've made a small example using the SHORT_DESCRIPTION on to refer it to the bug inside a template -works out quite nicely IMHO. Please click to get to the subpage and the example
 * Bottom line if we use a short descriptive title for each bug.. And somehow split the description from a blob of text about the bug we end up with an actually readable page ;D
 * There are a few ways to do it, I was initially thinking about templates and I made 2 examples, however I can imagine a third I just don't know enough about wiki to make it work - Hopefully someone better with templates/tables/? as I am can hop on the bandwagon and pitch in some more examples on how to get the result where bugs are listed in a short description... For example a collapse able table, it starts "collapsed" so you can only see the short descriptions, when you click the description the full text (repro steps, workarounds, other info, etc.. are shown)
 * My two examples are basically splitting the blob into a description and an entry for each bug using a template. templates either in-page or as sub-pages.. But there are probably better solutions.. the templates are nice in a way that they aren't hard to use and don't have to make the page hard to edit (which it could become if everything gets clunked in one big table for each category. And I made my template so the first variable is the short description, the second variable is the description ..so its relatively easy to reformat all the existing entries to use it...
 * Can someone remind me how to make bits of table collapsed on load ?
 * Known_bugs/formattest
 * Oh It got lost in the snipping - The @jeb_ was to have a field to place links to the Reply in this page that was made by Jeb.. But it could of course be renamed and used to link responses from whatever place Mojang (not specifically jeb or notch. but any official reply about anything) used for a specific bug - whether it be this page or something on getsatisfaction or .. w/e
 * priority might not be awesome indeed, since its equally hard to know what mojang thinks are important bugs - It might be better to turn it into an "intended fix eta" field (so if we know they are working on some bug to fix before the next version we can add that bit of info ..  But again, It was a "quick"  mockup, I put some thought into the fields but it wasn't my goal to make it perfect all at once ;p Lalophobia 10:32, 5 May 2011 (UTC)


 * What we really need is a proper bug tracker; then we'd get bug indexes, a place to put full descriptions/discuss the bug/offer fixes, and ability to track the priority/severity/assignees/affected versions/whether it's been fixed or not, in an interface designed to do just that. Trying to implement a poor BTS on top of MediaWiki doesn't strike me as a particularly great plan. Dagger 12:02, 5 May 2011 (UTC)
 * Well ..although I agree on that [An actual BTS is the best solution to manage bugs), this list is recognized by Mojang as a good list (content wise) and it has their attention.. Currently it's even more clunky as getsatisfaction (Although getsatisfaction has a lot better layout its just overwhelmed with topics (247 PAGES in the Common problems sections index - so thats unusable as a tracker because of polution not to mention that there is very little to say for it in terms of anything you'd expect a generic BTS to be capable of (because its a feedback system NOT a bugtracker - period)) .. so until the switch is made to an actual bug tracker we're still stuck with whatever Mojang says they are looking at ;)  ..
 * And this page does need work because it's rediculously hard to plow through just to read, and there is overlap in SSP/SMP etcetcetc, and it's not 'quick and easy' to look through all existing bugs to see if your bug is there before posting.
 * So we might as well discus the best intermediate solution ,imho Lalophobia 13:13, 5 May 2011 (UTC)
 * PS: Also, if we swap over to some random BTS, eventually someone would have to change this page a list of bugs that are active on the BST. And that's very likely going to happen based on a short description ;) ;) ;)  (also then there is a disadvantage that we'd need to figure a way to sync the BST and a list on the wiki unless we totally abondon the list and just keep everything in the BST )
 * And it doesn't have to be a 'poor BTS' because the wiki has some powerful mechanics, my examples are REALLY basic.. because my wiki skill is equally basic; however I did design the template with a strong point in mind..

Notice this first example is just using variable 1 and 2 - short description and 'the original blob of text' So it's really easy to start using and work out the details of the bug in later on ..


 * Let's carry on the talk please, I think I've supplied some adequate idea's and did too much typing about it ;) ..
 * .. So it needs more feedback


 * I've whipped up a version which fits together nicely. You can preview it over at my projects page. If we use your current version the page will be massive, so we need to keep each initial thing to one line.
 * I'm happy with the design at the moment, what I need now is some more fields to fill in that blank space. – ultradude25 ( T at 15:55, 5 May 2011 (UTC)
 * It would only be massive if we used Example2 not if we use [| Example 1]
 * But Cool, you used that collapsable thing that I couldn't figure out / wasn't working the way i wanted it ... Because you still gave me the code to borrow .. have some of these [[Image:Cookie.png|24px]][[Image:Cookie.png|24px]][[Image:Cookie.png|24px]][[Image:Cookie.png|24px]][[Image:Cookie.png|24px]][[Image:Cookie.png|24px]]


 * UGH...found the collapsable table on the regular wiki and it's not working ... HELP ..
 * Best practice would be to have it nested, so its just the description, then if you click show it shows short description+ text + repro steps + notes ... with another 'show' button

and if that is clicked the other attributes are visible like priority and version .. Tell me how to make it work and you get a box of cookies :)
 * I just gave myself half a box of cookies .. Ha !  but now the next bit is the nested collapsable table
 * This may be mean, but I think the thing I like best about the nested table design is that it's probably complicated enough to provide a small barrier-of-entry to prevent some of the garbage that gets added to the list on occassion :P Like, some random guy will have to do some small amount of thinking before adding "omg I totolly sawd this bad bug where creepers expoded on me!111" --Warlock 16:16, 5 May 2011 (UTC)
 * I think those folks are already mostly stopped by the registering process.. It's acceptable if there is a tiny amount of code people need to take into account, but It should be usable by anyone in the long run (since the more things that can go wrong will also mean the more time lost by admins restoring the pages after someone messes up..)
 * Dont forget the goal is to make the page better (readable), not more complicated because of an occasional moron edited in a bullcrap bug ;)
 * Now that I finally have at least one part of the collapsable tables working my template should suck a lot less .. I'm trying to refrain myself from comparing the template I did with the template from Ultradude25 because we its just another way of using the templates.. The way that its representated is of course important in the long run but right now i'm more concerned with the concept, the mechanics and impact, not the visual aspect of it - at all..  - however, there are a number of things i really like about his example.. because it's basically the inline table version that I was asking for .. and it seems to generate some of the markup (the colors of severity) based upon what is filled in .. So he's a lot better with the tables and templates but when its broken down into components its a more suffisticated version as my general examples.. - and i dont mind that at all , i'm not trying to win internetz here. I just figured the main page desperately needs an overhaul and we're talking about possibilities here  ^^
 * PS Again i have the feeling that this already long talk page just gets really long by this formatting debate.. Is there an even better and more central place where we should discuss this or is this still fine ? Lalophobia 09:45, 6 May 2011 (UTC)

People deleting bugs.
Some useful confirmed bugs have been deleted recently. Is this vandalism? YoshiRider9000 02:56, 6 May 2011 (UTC)
 * IDK. I just seen the 16 edits that removed bugs as well. Cool12309(T 03:08, 6 May 2011 (UTC)

Wow it looks like a ton more got re-deleted. :/ YoshiRider9000 21:56, 7 May 2011 (UTC)
 * Seems to be a disagreement on what constitutes a bug by Shukaro. I sent the user a message to check the talk page, but if there's no response, we should just relist the bugs. LTK 70 18:22, 9 May 2011 (UTC)
 * I don't know, if it's intended behavior (which, due to limitations in the code, it sort of is), I don't really think it's a bug. It's not exactly "correct behavior" either though, so I'm not sure how you'd classify that.


 * Side note: IMO, "fixed bugs" absolutely do not belong on the list. If it's fixed, it's no longer a bug.  These are sort of already tracked in Version History, though probably not well. --Warlock 18:46, 9 May 2011 (UTC)

Lightning and pigs
On my Bukkit server at least, pig turn into as many pigmen as lightning strikes NEAR them. So, one pig can become a LOT of zombies. Sir Speshkitty 12:15, 6 May 2011 (UTC)
 * Edit: So, "someone" just spawned 100 pigs. Then MASS lightninged. Screenshots will follow :D Sir Speshkitty 12:19, 6 May 2011 (UTC)
 * instead of "one pig can become a LOT of zombies" you mean "many pig can become many pigmen with just one lightning strike" ?

I think what he means is that if you have one pig, the amount of Zombie Pigmen that spawn depends on how many lightning strikes go near the original spot of the pig. Is that right? Tanksenior 10:09, 12 May 2011 (UTC)

Wolves not respawning on ice
Shouldn't we add that wolves do not respawn while the player is on ice? Sakishrist 07:35, 7 May 2011 (UTC)

Maybe not a bug since ice is transparent. C ali nou - talk × contribs » 23:29, 7 May 2011 (UTC)

Edit: Indeed, wolves do not teleport to the player when walking on ice. As soon as you set foot on land they appear right beside you. But is it worth listing? Nothing is stopping the wolf from walking along with you. LTK 70 18:19, 9 May 2011 (UTC)

A friend of mine had the issue of his wolves teleporting BELOW the ice multiple times(SSP). Don't know if this is a bug or not though. Tanksenior 10:11, 12 May 2011 (UTC)

Nether Portal spawned deep underground
For me, after building the portal the travel to the Nether, I traveled through and my default Nether portal was Deep underground.

I have been mining diagnally-upwards for a while now to try to get to the surface, but it occured to me that i could be digging up to a lava pool so i cautiously stopped and consulted Minecraft Wiki. I couldn't find anything that linked into another case of this happening to anyone else so I have decided to ask here.

I wonder if this has happened to anyone else and perhaps this is a bug; known or unkown, but like I said, I couldn't find anything.

Anyone know what's happened?

For more details:

- The cavern i was teleported to was reletively small, and took approximatley 15 seconds to walk from one end to another. - The cavern wasn't actually tall enough to hold the whole of the portal but instead buried the bottom row of obsidian blocks. - There is nothing in the cavern but Netherrack and, of course, the portal. - I have dug about 100 blocks by travelling diagnally upwards. <*Edit* Now i am just travveling horizontally and I have now been mining for about 10 mins straight with a stone pickaxe and still not getting anywhere - I am now pressing the 'F' key every now-and-then to see if there is any lava or anything around, nothing yet.>

p.s. I have only been playing for 3 days now so if this is supposed to happen the I am sorry, though it is strange

Xx snipaguy xX 23:42, 7 May 2011 (UTC)Xx snipaguy xX

It's not uncommon. Portals spawn in the Nether relative to the height where you entered them in the overworld. If you built one at the top of the map, you'll probably get a portal in the top layers. Same goes for the bottom of the map. It's unlikely that you dig into the lava sea though, since there are hardly any caverns under them.

In the future, you might want to take questions like these to minecraftforum.net. Wiki talk pages don't usually concern individual problems. LTK 70 22:40, 8 May 2011 (UTC)

Water sometimes fails to turn lava into obsidian
Sometimes water falling on lava does not turn it into obsidian. Reproduce: I suspect this happens every time the water is falling on the lava instead of flowing on it. --GALAKTOS 09:13, 8 May 2011 (UTC)

Game limitations
I saw some bugs listed here that were removed after a while for example that water doesn't flow through open doors. These are no real bugs but the logic is wrong. In my opinion we should give them an own section at the page because there is a chance that they will be fixed in some time too. --Sworddragon 14:01, 8 May 2011 (UTC)
 * I agree that they should be kept listed. Just because the game doesn't currently support blocks being non-exclusive to water (for example) doesn't mean that we shouldn't report it. It's not how you would expect it to work, and it's definitely not intentionally so. LTK 70 21:51, 8 May 2011 (UTC)

What constitutes a bug, in my opinion, is when a feature that is in the game (or at least supposed to be in the game) is not functioning correctly, or is totally absent. For example, the Nether, in SMP, is bugged because it doesn't work at all, when it is supposed to. Another example would be items clipping through non-solid non-cuboid blocks such as glass or slabs. Items are supposed to sit on any surface the player can, but they don't, so this too would be a bug. Shukaro 20:13, 9 May 2011 (UTC)
 * See, I don't know that I consider SMP Nether to be a "bug." If it was actually supposed to be there, and it didn't work, then yes, it'd be a bug.  But it's not supposed to be there - Notch didn't finish it (yet).  It's an omission or unfinished feature maybe, but it's not really broken.  And to be picky, the Nether works in SMP, just not Portals (you can setup your server to be a "Nether" server, and there are also plugins/mods to enable Nether/Portal functionality to varying degrees of accuracy as well).


 * I don't know though - all this is really just getting into symantics. --Warlock 21:04, 9 May 2011 (UTC)

By that definition I do think that the case of water flowing past or through blocks counts as a bug. Those are the ones I'd still like to see listed. If water is blocked by a ladder, then water is simply not functioning correctly. It's true that this is a limitation of block mechanics, but that doesn't mean it shouldn't be fixed. LTK 70 21:28, 9 May 2011 (UTC)
 * another fun example would be a single fence (as a pole) surrounded by water blocks.. Lalophobia 23:19, 12 May 2011 (UTC)

Bugs are differences in the actual behavior of a program from it's intended behavior, or maybe has unforeseen complications. You may not like the fact that water cannot exist in the same block as ladders, doors, etc. but there is no way that Notch did't deliberately and knowingly design the game to work that way. It is not an "error" -- it was a decision. Complaints that you don't like a game's design decisions don't belong on a bug list-- they are feature requests--Eleazzaar 17:35, 12 May 2011 (UTC)

Archiving the page as is
This page is now a stunning 98 KB, which is a bit more than 3 times the "safe limit" for some browsers to view. This page should be archived so as to cut down the size of this page. Cool12309(T 22:03, 9 May 2011 (UTC)


 * We could merge SSP and SMP because many bugs are listed twice for each. We could also try to cut back on unnecessary pics or links taking up space. YoshiRider9000 22:43, 9 May 2011 (UTC)
 * Oops, I didn't mean the main page, I meant this talk page. THIS needs to be archived (why would you archive a main page?) Cool12309(T 01:36, 10 May 2011 (UTC)

Color/colour; gray/grey; etc. needs a hard limit
We need to have a hard set for color/colour and etc. things all around the wiki. We should go by what Notch uses, but I'm not sure what he uses. Cool12309(T 22:03, 9 May 2011 (UTC)
 * He uses "gray"(as per the item gray wool) and probably uses "colour", since "color" is primarily a U.S. spelling. - Alphap T ~ C 22:13, 9 May 2011 (UTC)
 * The game does indeed use "gray", so I'd go with that. "Colour" though, ick... I have never been a fan of that spelling. --Warlock 14:48, 10 May 2011 (UTC)

SSP + SMP Combined Section Added!
The long awaited SSP and SMP section is now added! Please move the bugs that are in both the SSP and SMP sections to the new section. Cool12309(T 01:53, 10 May 2011 (UTC)
 * I moved a ton over that I was sure occurred in both (or that were otherwise listed as such in the bug description). I'm quite sure there are more that need to be moved, but I didn't want to start making assumptions.


 * As a note, I didn't look at the SMP section at all, so there may be some leftover duplicates there (for the bugs that got written up in both sections) that were already moved from SSP to the new section. --Warlock 14:45, 10 May 2011 (UTC)


 * Wait, what? I thought the SSP and SMP sections were already mutually exclusive. Why does this page even need a 'combined' section? Single Player Minecraft is the exact same game as Multiplayer Minecraft, and the bugs are an extension. I'd be very, very surprised if you can show me a bug that exist in a SSP feature but not the equivalent SMP feature. Portals don't count. LTK 70 20:42, 10 May 2011 (UTC)

An example of an SSP only bug is opening your inventory, holding down left-mouse button, close inventory while holding and you can break blocks without hurting mobs. This doesn't work in SMP but i do think they should say SSP only bugs instead of just saying SSP bugs. YoshiRider9000 22:56, 10 May 2011 (UTC)


 * Ah yes, although there are particle effects when attempting to replicate this in SMP, so apparently they're still related. Even so, SSP-only bugs are a rarity, and don't warrant splitting the page up in even more topics. It's already pretty hard to keep redundancies out of the bug list as it is, so I really think the old format is a better way to go. LTK 70 13:33, 11 May 2011 (UTC)
 * If we have a combined section, then in theory, it should reduce the page size, by having it said only once and not twice. This allows the page to be loaded faster. Cool12309(T 00:32, 12 May 2011 (UTC)
 * Er, no. Almost all of the bugs listed in SMP are exclusive to SMP. I've made an effort to keep duplicate bugs out of the SMP list, and I'm sure other people have as well. If anything, a three-way split will cause even more duplicate entries. LTK 70 12:26, 12 May 2011 (UTC)
 * I think the combined section should be moved to the top as well as SSP and SMP being changed to SSP-only and SMP-only so ppeople can notice it better and would akso make things more clear. YoshiRider9000 02:03, 12 May 2011 (UTC)
 * I do agree that the combined list should be on top, I don't want to keep hammering on that reformatting project.. but in the meanwhile; what do we do with solved bugs?? I've spotted at least one already while glancing over the page - I do not agree that solved bugs should just be removed. Making a solved bug entry to the page might be an option (also makes it easier for folks to edit), but the list isn't short right now so with that in mind it might not be great..  Ah sod it, we need to do some more talking about that formatting project and go forward with something so just a description is shown- and not a blob of text per entry  Lalophobia 22:49, 12 May 2011 (UTC)

Bug Page Cleanup - 5/13/11 - 5/15/11
I am planning on doing a cleanup on this page (not the talk page). I do not mean formatting (although I might do :P), but I mean going through and testing each bug. During the cleanup period (May 13th, 2011 (Friday) - May 15th, 2011 (Sunday)), no changes to the page can be made. The approximate times for the 3 days are listed below:

May 13th: 9 PM (21:00) GMT 0 - 4:30 AM (4:30) GMT 0

May 14th: 5 10 PM (17:00) GMT 0 - 4:30 AM (4:30) GMT 0

May 15th: 5 PM (17:00) GMT 0 - 4 AM (4:00) GMT 0

Please note: I can't test the Mac OS X bugs, as I don't have a Mac OS X; nor can I test the 'sometimes' bugs, because I don't have time to test a 'sometimes' bug that takes 2 hours each.

Thank you for doing this. It will reduce the amount of work Notch has to do to test these bugs. But why did you remove these two bugs: I can easily replicate both of these. Are they duplicates of other bugs? Functor 01:53, 15 May 2011 (UTC)
 * Destroying a minecart while you are in makes half of your body sink into the ground. If the ground is only one block thick, you will fall through completely. If the minecart is on the bottom layer of bedrock, you will fall off the bottom of the world.
 * If you hold the left mouse button down while holding a item, then open your inventory, still holding the left mouse button, and then close your inventory, as long as you don't release the left mouse button, you are able to break blocks without the swinging item animation.

Beds in SMP
I'm not sure if this works in SSP, but in SMP, if you try to sleep in a bed that is surrounded by half blocks then it says that the bed is occupied. Going further, if you sleep in another 'legal' bed then you are teleported to the 'illegal' bed, even if you don't sleep. Using this, a player could easily get out of a situation by placing a bed and teleporting back to safety; so maybe it's not all bad.

Invisible player in SMP
From the bugs list : Occasionally players will become invisible to each other at random times for no particular reason and will subsequently reappear just as randomly. Players may still interact with each other (damaging each other, mining terrain, etc) but will be invisible.

This bugs is really a pain for PVP servers. It happens often and players must disconnect/reconnect to avoid it.

But in fact, it's not random. You can find an explanation, how to reproduce it, and a quick fix on the server side here : http://minecraft.galaxy-games.com/content/invisible-player-issue --Tikkub 12:12, 17 May 2011 (UTC)

Taken from the main page: "In Multiplayer, a player can see 2 players, one is moving and one is not moving. This can happen when a player teleports to somebody suddenly. It creates lots of lag, and then you will see another player from where the player teleported." I don't get this a lot with other players on SMP, but it does happen to me a lot with falling gravel/sand and monster spawner fire. They seem to be client-side, and can be removed by reconnecting. I'm not getting any lag from it, though. 71.46.222.254 13:40, 28 October 2011 (UTC)

Launcher Bug
Hm... I have a Bug regarding the Minecraft Launcher: The Login and Options Buttons have transparent backgrounds if no Windows-Style are active (link), where should I put it under the Bugs Page?

Powered Rail by Slab Dud
When a powered rail is placed next to a slab, the slab doesn't count as a blocked side, and so when activated, it will not trigger a resting cart to accelerate as it should. Chloë 03:32, 19 May 2011 (UTC)
 * on the bright side,the whole launcher might be an unintended feature to start with ;) .I've tried asking notch and jeb if it is a feature or bug but have not received confirmation of anything.
 * If you place a normal track next to a block and put a cart on it you may notice that the cart pokes a few pixels into the block. What i think might happen with the powered rail because the cart normally shouldn't travel into a block it tries to adjust itself but it can't due to the braking of the unpowered rail. when the power is turned on the cart can move that pixel trying to adjust itself and in the process has 'momentum enough' to trigger the boost from powered rail and we see a 'launch' occur.  Lalophobia 10:02, 20 May 2011 (UTC)

Repeater Power Displacement
When a repeater drives directly into the side of a block, not only is that block powered, but wires running on either side of the block erroneously get power as well, though blocks in the same positions will remain unpowered as expected. For an example, see (Is it acceptable to link an external image so long as it's on a discussion page?)  Chloë (T 01:34, 20 May 2011 (UTC)
 * Not a bug, it's powering the block and therefore the sides of the block. Cool12309(T 17:00, 22 May 2011 (UTC)

Pre-Emptive Bug Removal
It might be a good ideal to color code the bugs that Notch has claimed to have fixed for 1.6 here. It would be informative more than anything else. Probably just blue highlighting bugs Notch listed as fixed and adding a note at the top of the article stating that bugs highlighted in blue are scheduled to be fixed in Minecraft 1.6 --  Techrocket9 00:03, 24 May 2011 (UTC)

It would be a nice and informative feature.
 * Sure, go ahead. Nice idea.--Coupon22 21:49, 23 May 2011 (UTC)

I agree with this idea.

Well, if not blue how about a different color. Grey (faded almost) perhaps? --Techrocket9 19:40, 24 May 2011 (UTC)
 * Yeah, something... the current notation is practically invisible and might as well not even be there.


 * Edit: Of course, all this will be moot in like a day or two anyways. --Warlock 19:43, 24 May 2011 (UTC)


 * Changing text color to note something is generally a bad idea. If you want to see where the note is currently, do a full-page search (CTRL + F in most browsers) and search for the string "[fixed 1]" (sans quotes).

 * Administrators wouldn't necessarily be able to do so any better than any normal editor. Regardless, though, archiving is generally pretty easy - just choose a cutoff age (e.g. no replies in 2+ months), and copy all threads older than that to a subpage of this page (e.g. Talk:Known bugs/Archive 1). Then place a link to the archive at the top of this page. It doesn't really have to be fancy or complicated. =) 「 ダイノ ガイ 千？！ 」? · ☎ Dinoguy1000 20:08, 24 May 2011 (UTC)
 * An alternative idea : archive the whole page&talk with 1.6, retest bugs and those that are still in get replaced on the list.. since it's a whole lot of work to sort out everything based on date and it will still not be flawless if something relevant gets archived or not - and might not be really useful to use a arbitrary date like '2 months ago' -the patch 1.6 is a clear landmark. We could start with a clean slate and start with a blank page with just these headers on the article page

1.6.2 assorted bugs
I'm just gonna throw in bugs I find here...


 * Lighting doesn't update for removed blocks (the air where the block was has lighting 0 until a torch is placed to reset the lighting)
 * Abnormal CPU usage in server (one core goes to 100%; one thread stuck in infinite loop?). Only while a user is connected... (To check: Does it use one core at 100% per user, or just one core when any number of users are online?)
 * Compression of chunk data means more laggy subways (due to fast speed of minecarts)
 * Furnaces are behaving strangely
 * Standing still in a portal after being portaled shows the whirly animation (but it never portals you)... Being portaled through, the whirly animation shouldn't play until you step out of the portal and into it again.

Standing in side-mounted torch disables actions
I noticed that if I stand inside of a torch (place a torch on the side of the top block of a two-block high space and stand so that the characters head is in the block), I can't place blocks, enter chests/furnaces/workbenches etc and the only thing I can do is destroy the torch which I'm standing in.

Suggestion: Requested Features list
I was thinking, can't we, in lieu with this page, create a Requested Features page?

Notch said he'd look here for bugs, well, maybe such a page could re-order his priorities on new features.

The page should include some introductory text, stating that things like 'more achievements' shouldn't be on that page.

I myself have a few ideas for this page:


 * A Biome Reader, similar to the clock and compass, which has 2 dials, the one on the left shows the temperature, the one on the right shows the humidity. In case something grows only, for example, in a desert, this reader can help you find one.
 * A Mineral Reader, like the Geologists in Settlers 2 it should be possible to get some information on what's in the ground. Something similar to one of the devices sported in the IndustrialCraft mod.
 * Binoculars or Telescope, cause, well, if I'm king of my castle I want to see what's below me!

Instant death when riding a boat into a Hatch
So I was playing around with Hatches, and decided that I could make a cool dock making use of hatches preventing water movement around them. I made a standard Drawbridge design [2x3 hatches] And had the all open. Upon sailing a boat into the space, I insta-died. [SSP, Windows 7 x64Bit]. I tried to duplicate it and have only managed to duplicate the insta-death twice out of about 20 attempts. --DwarfWoot 20:33, 27 May 2011 (UTC)

Furnace: Infinite fuel
The bug is present in 1.6.4 SSP. I have a piece of coal inside a furnace, and it does not get consumed when I smelt/cook something. I've actually smelt about 50 iron ingots, 20 golds and some porkchops with that single piece of coal (nice?). I built more furnaces just to check if it was the same with them, but they consume the fuel as supossed to. Is anyone else having this (nice) bug?

Just FYI, the piece of coal does not disappear with the furnace burning forever. Actually, the furnace reuses the same coal as needed, but the burning animation stops when the coal is "consumed", its just that its not really consumed.

Cleanup of all "Sometimes" or "Occasionally" Bugs
Due to the sheer number of bug fixes Notch put into 1.6, I think there should be a cleanup of all bugs that are hard to test. Specifically, the bugs that happen "sometimes" or "occasionally" should be removed. If someone runs into these bugs again on the most recent version, they should re-add those bugs WITH PROOF that the bug happens in the most recent version.

Gravel into lava
The bug I added regarding lava falling into lava was removed on 21:22, 2 June 2011. This is a legitimate bug on 1.6.6, can anyone explain why it was removed? "Bug: Gravel (SMP) * After placing gravel in lava and digging out, burning gravel will appear floating in mid-air." I did not confirm this happening on SSP, so I didn't add it to the both section.


 * Meh sometimes random stuff gets removed by mistake just add it again.


 * Well I figured maybe it was deleted because it was not easily reproducible and fell under the category of the "sometimes" and "occasionally" bugs topic. So, I spent the past 8hrs trying to reproduce it but couldn't. I did get a screen shot of the original bug. Sorry I didn't have the debug screen up to confirm, but this did happen in 1.6.6. I suggest leave this issue on the talk page and see if anyone else has seen this same bug.

Re: Boats
"1. If you manage to stand on your boat while it is under water, the boat won't move to any direction. 2. If you go under a water stream your boat will accelerate and rise upwards."

Black Arrows
when i was playing minecraft I shot a arrow at the bottom of a block and the arrow turnt black. --Taco1945 19:31, 17 January 2011 (UTC)

Yeah, that has happened to me too, although I do not think that is a bug. I think that might actually be a glitch instead...if that is possible. I think it has to do with the arrow not supposed to be like that...If you right click a door with a boat in your hand, the boat turns black and on top of the door... Stinkbug22 16:34, 27 March 2011 (UTC)

Entities take on the lighting shade of the cube they're in. What's happening here is that the arrow is “in” a solid block instead of the air, which is always black. You can also see black entities when a minecart rolls into a solid block (due to curves/ramps), or in particularly glitchy multiplayer where mobs don't cleanly jump up edges. —KPReid 17:24, 27 March 2011 (UTC)

Trees Deleting Slabs
I've noticed in Single player that When a tree grows from a sapling, and grows near a slab, they can grow over and delete the slab. I've only seen this happen with Smoothstone Slabs, but I guess it could happen with other ones.

Has anyone else seen this occurrence, to the point where we should add it?

Not only slabs where the problem for me, every block can be replaced, though it is rare. Haven't tested with bedrock and stuff, but it happened with cobblestone. --Lulloman 07:50, 26 September 2011 (UTC)

Terrain_Generation bug false?
i believe "Large sections of "floating blocks" have been generated on new worlds for some clients. Here is a screenshot from a world in 1.5_01. The error only seems to appear in coastal areas in a large scale, floating blocks include: dirt, leaves and logs so far with select ores. Snow blocks seem also to appear on water.(Modifications within the screenshot have not shown bugs before and therefore I did not believe that they contributed to this bug.)" to not be a real bug since Zans Minimap (as displayed in the screenshot) WILL corrupt the terrain generation when multithredding is turned on in SSP. --Yssaril 18:18, 3 June 2011 (UTC)

Tall Grass
I had some tall grass on my roof and part of it was sticking in my house. Would this be a bug? YoshiRider9000 23:44, 4 June 2011 (UTC)
 * If it is on you roof...the mental image is that it can't be in your house unless some of your house is above the roof in question. Need to be a little clearer on your description.  What I think you are saying is that you have a dirt roof (interesting) on a lower floor and part of it is in the wall of an upper floor.
 * That said, the answer is yes and no. The tall grass is meant to be placed randomly on the blocks so it breaks up uniformity and looks a little more natural, unfortunately this means part of it will overlap a block, but if there is no block there or a wall it can look odd.  It's really just a trade-off.  I would just trim it.

SMP v1.6.5 Ice and arrows bug
We've discovered that breaking a block of ice with arrows stuck to it causes the following error:

Client quit bug?
I'm having an issue with the client. And am wondering if this is a bug. I'll be playing with the downloaded client in SSP and the game will immediately go to saving chunks and shut down and exit. No going to menu. Just shuts down and exits to desktop. A few of my friends have reported this happening to them once or twice out of pure random. But this has happened to me three times today. The third time. I let the client sit there and it did it about 5 minutes into gameplay. Its now just started acting up. Gemini523 14:52, 11 June 2011 (UTC)

"Wolves preventing passive mob spawns" bug is also in SSP
The "Copious amounts of tamed wolves in a concentrated area prevent the spawning of nearby passive mobs (easily up to 10-chunk radius)" bug is only in the SMP bug section, but the bug exists in SSP, too (I have 21 wolves in my single-player world, and see no animals that are less than 10 chunks away from them).

The bug list currently lists "Since 1.7 it is now possible to climb ladders with one block leaps." in the ladder section. I tested this and it did not seem to be the case. If someone else confirms that this is a misbug it should be removed. Techrocket9 07:00, 1 July 2011 (UTC)

General bug in the "Out of memory" detection?
On one of my machines (2 GB RAM, Windows XP, running Minecraft.exe) the game quits every few seconds with the "Out of memory" screen. After may tries I found when I run the game with -Xmx512M it works but it does not work with -Xmx1024M (which seems to be the default) or more. I have to reduce the amount of memory to be able to run the game without "Out of memory" warnings. From what I understand this is because there is not enough memory left for things outside the heap if the heap is to big. From my point of view this is Is this enough information to be added to the list of known bugs? --Mrheat 09:35, 1 July 2011 (UTC)
 * 1) a bug either with the default value being to big (should be 512 instead of 1024 on machines with 2 GB RAM) or
 * 2) a bug in the source code that is responsible for displaying the "Out of memory" warnings.

Trapdoors collision box to big to be combined with ladders
There is currently no section for trapdoors/hatches. My problem is: If there is a trapdoor above a ladder with the hinge of the hatch pointing to the ladder it's not possible to climb up easily. The players head get stuck on the small side of the opened hatch. Same problem if the hinge of the hatch is on the left or right side: You have to move to the other side (being careful to not fall from the ladder) to avoid being stuck under the opened hatch. I call this a bug because from what I understand this should be a valid use for hatches. --Mrheat 10:07, 1 July 2011 (UTC)

Unexpected Crashes in Windows 7
My Minecraft sometimes crashes unexpectedly. --Amigopen The Gemini! 02:03, 5 July 2011 (UTC)

Running out of memory and Java Errors Aswell

Using on or doesn't work but the item is consumed bugs
I...don't really think these would be 'bugs', just 'quirks' in gameplay. If you use something on something...of course it would be consumed. If you use water on solder expecting it to fuse two pieces of metal together...you consume the water but it didn't work...it's the same concept here. If you use flint and steel on glass and it doesn't work...you still used the flint and steel but it didn't work, but you still used it. Same goes with bone meal on saplings with not enough room to grow. you still put the bone meal on the plant but there wasn't enough room to grow. Maybe a message to the player would be better here, but I really don't think these are bugs. Jguy 11:12, 6 July 2011 (UTC)
 * But this is minecraft, not a real world. The most things that Notch added were for simple and nice gameplay, so I think it is a bug.

Blinking minecart in SP
When looking backward in a moving minecart we can see the minecart blinking. This bug is surely in SMP too, as its only graphical (so up to the client) and despite being minor is really annoying. Also the bottom of the minecart texture changes when the direction changes : this lead in a weird changing texture while moving diagonally. (those bugs were present since the 1.6 at least) --Tino135 13:45 (utc), 19 July 2011

Swapping items while sneaking not a bug?
Opening the inventory while the player is sneaking will cause you to not able to click and drag items. Anything clicked will instantly be taken to or from hotbar. Survives world reloads and client reloads. This only applies if the user's sneak key is SHIFT. I'm pretty sure this is not a bug, because shift-clicking an item is meant to send it to the hotbar anyways. Since you are sneaking with the shift key, this should be expected. Rgamer35 02:51, 29 July 2011 (UTC)

'Saving Chunks' Crash
Okay, so I've tested it many times now, and I've got a fun little crashing bug here. On occasion Minecraft will stop in the middle of gameplay with a 'Saving Chunks' screen. After that, the screen goes black until I exit the program.

As I said, I tested. So, I know what's causing it, to an extent.

The crash occurs when I open my inventory, specifically. It seems that moving the cursor around for selecting items is what causes this. As such, opening your inventory and moving your mouse pointer around in there like crazy causes the crash almost instantly.

Even further, I've pulled Minecraft open with a .bat to monitor what exactly is going wrong when this happens. When the crash occurs, the following is displayed in the .bat's console.

Code: java.lang.ArrayIndexOutOfBoundsException: 4 at en.a(SourceFile:29) at iz.l(SourceFile:226) at id.a(GuiContainer.java:76) at ue.a(SourceFile:32) at px.b(EntityRenderer.java:451) at net.minecraft.client.Minecraft.run(Minecraft.java:575) at java.lang.Thread.run(Unknown Source)

Anyone else having similar issues or have an idea what might be wrong? I didn't have this issue before 1.7's release.

Maybe you were using a mod that did use a block or metadata of a block or an item that does not exist anymore. Trying to search it's tooltip will crash it, I think CosmoConsole my page! my talk! my contributions! 19:13, 7 August 2011 (UTC)


 * I had this bug since 1.5-1.6.6 and in 1.8.1 reintroduced while in creative mode. Don't have the codes, but I think it depends on how many items you have in your inventory(that's why it would crash in creative mode, I think).

Hand bug
Has anybody else seen that the hand will be in a different stance in specific locations and rotations? I've not seen it in SSP but in SMP.



CosmoConsole my talk!.My contribs! 18:58, 7 August 2011 (UTC)


 * I have seen this bug in SMP, one you exit the boat or minecart, or get off a pig, opening and closing your inventory should fix it. --IPeer 16:09, 10 August 2011 (UTC)


 * No, this occurs sometimes for me all the time, depending on the stance, and inventory does not fix it. CosmoConsole 	<font color="#D2691E"> my page! my talk! my contributions! 16:15, 19 August 2011 (UTC)

"You can't hold down the left mouse button to continuously attack anymore." "You can't hold down the left mouse button to to break a minecart anymore." These are basically the same. Also applies to boats. 71.46.222.254 17:28, 28 October 2011 (UTC)

Removed Taming Wolf in Water on SMP is impossible.
Have tested the it, and proved it wrong. Taming a wolf while it is in the water is possible.

Fire spreads through walls
Here is a demonstration video: http://twitvid.com/DEQFI (keep cool, that was recorded on my crap-top.)
 * I have this error since Notch "nerfed" fire in one update and it keeps setting my roofs on fire. I cannot find anything about this bug here, so we might want to add it. --eiszfuchs 13:10, 19 August 2011 (UTC)


 * This bug only seem to occur when fire is placed to Netherrack. I've tested in 1.5_01 with normal fire and nether fire, nether fire spread through walls, normal fire didnt. --Lulloman 07:53, 26 September 2011 (UTC)

Black Screen.
I believe there is something wrong with my mac computer, but it is new and everything is updated. Whenever i try to play minecraft in the browser, it asks to run this file and i run it, then it asks to run the file again 4 times. After the first one, the game screen turns black. When i pressed escape, it still released the mouse as it should and when i pressed the area where i would normally be seeing BACK TO GAME, it relocked the mouse. Also, when i tabbed out to check out the problem on wiki, i began to hear the mincraft "elevator music", so it is only a screen problem for sure. This problem is not new. Minecraft has had this problem always on this computer. Any help is golden. –The preceding unsigned comment was added by Jboy814 (Talk&#124;Contribs) Please sign your posts with

Out Of Memory
Minecraft is running out of memory alot. I have java set to 1000mb. That should be more than enough for minecraft. In 1.7 I have no memory problems, when I enter 1.8, I run into memory problems and game crashes.


 * 1000MB is far more than Minecraft needs, thus you're going to get lots of out of memory errors, due to the lack of garbage collection. Lower the memory to something more appropriate, like 200MB. – ultradude25 ( T &#124; C ) at 07:24, 10 September 2011 (UTC)


 * I was at default (512) and I was getting errors. So I bumped it up. Thanks though, I didnt know that Too much memory could be bad.


 * It's the way java works. A lower memory forces it to do garbage collection more often, which makes Minecraft use less memory, and thus not run out of memory. You'll also probably get out of memory errors if you're using 32-bit java on a 64-bit system. – ultradude25 ( T &#124; C ) at 08:47, 10 September 2011 (UTC)

Bed Glitch
When you start sleeping in a bed and destroy it before you fully go to sleep (while the screen is turning black), you can get out of your bed normally, but be able to somewhat walk into walls. I was able to go directly into a wall. I did take damage, but I walked to the other side of the wall.

Random World Generation (Creative mode)
I've created some random worlds in creative mode and get the same world most of the time. The Seed generator seems to be bugged. It seems to create seed: 6921607382888931028 multiple times when you create a 'random' new world.

Thats would be a bit confusing for new people to this kinda thing, ya know? New guy has to look through 12 different sections to report his bug? Nice idea though.

General Unplayable Lag
Works on Linux, but on windows all of the game after the Mojang intro screen is unplayable due to the lag, roughly 1 frame every 5 seconds. Playing the game in offline mode however has no lag (manually disabling the network card before loading the game).
 * Strange. Going SSP or SMP on Windows doesn't make my computer lagg. --Lulloman 14:24, 26 September 2011 (UTC)

Piston interacting with player
The extended part of a piston makes problems in SMP when using compact contraptions. The player can end up inside the extended pistons, this could be fixed by making them solid?
 * Those are solid blocks, so it's strange that you are still getting stuck in it. Maybe the server's laggs caused this?--Lulloman 14:21, 26 September 2011 (UTC)

Defunct Furnace bug
I cannot reproduce the following bug in 1.8.


 * When Minecraft crashes, the items you placed in the furnace are lost forever.
 * Could not confirm. In 1.8, Furnace items save just fine when game crashed. (Solrac776 12:46, 14 September 2011 (UTC))
 * Same here for 1.8. (Ar3sTsK 01:31, 17 September 2011 (UTC))
 * I posted this bug, but it was still present in 1.7.3. This only occured when you placed it in the session when Minecraft crashes, not if you placed items in furnaces, then saved, and then load again and then Minecraft crashes. Anyways, fine it is fixed :) --Lulloman 07:55, 26 September 2011 (UTC)

Thunder and lightning sounds at Bedrock
Survival Singleplayer: While making a mine of my very own, I was 1-3 blocks above bedrock when a thunderstorm rolled into my world. I was able to hear the thunder and lightning strikes clear as day (Startled me!) as if the lightning was striking on top of my head, all the way from the bottom of the map. I could not hear rain or any other weather related sound effect, just the thunder and lightning, incredibly loud. 24.182.4.202 15:55, 14 September 2011 (UTC)

Mushroom Taking over 1.8 bugs
Since 1.8, Mushrooms (regular small ones, either brown or red) seem to congregate in order to take over the world :s No seriously the seem to grow and replace existing blocks, digging holes on adjacent blocks on the direct same horizontal level. If you dig a trench and gro mushrooms in it, the mushroom will spread enlarging this very trench :( Plus they seem to stop water flow some times ... I don't need to tell you that my automatic mushroom farm is not functional anymore, it is not important since growing giant mushrooms is far more efficient but still it does not seem right.

--Ar3stsk 01:29, 17 September 2011 (UTC)

My list of 1.8 (final) bugs
I will try to merge my list with the Known bugs page. All bugs found in the final 1.8. All tested in SSP only. --Mrheat 01:02, 15 September 2011 (UTC)
 * General
 * Horizon flickers (goes on and off) when riding a boat due to the boat floating up and down. [same in 1.9-pre1]
 * Fog flickers visibly when jumping on level 27. [fixed in 1.9-pre1]
 * If a chest is laying on the ground it is rotating on an edge instead of the center. [same in 1.9-pre1]
 * Lighting
 * Some solid blocks connected to lava emit light even if the lava is completely covered with blocks. Looks like there is a torch or lava but everything is covered. Can not be fixed by placing a torch or switching smooth lighting off. Can be fixed by breaking and replacing the blocks that emit light.
 * The floor below brown mushrooms is to bright (and flickers like it is lit by a torch).
 * Some torches in abandoned mineshafts do no lighting. Replacing the torch fixes the problem. [same in 1.9-pre1]
 * All animals and the players hand flicker between black and their color when walking around under trees. In my case this seems to be fixed by restarting the game. [same in 1.9-pre1]
 * Dogs are always black when they swim in water.
 * GUI
 * The icons in the hunger bar are jumping every few seconds on peacefull even if all bars are full.
 * Weather
 * Rain is rotated by 180 degrees. When walking from a dry to a wet biome it starts raining behind you. The raindrops on the ground are placed correctly (and therefor detached from the rain).
 * Mobs
 * Animals spawn in big groups only (groups of 5). [fixed in 1.9-pre1]
 * Terrain generation
 * Enormous amounts of yellow flowers everywhere but not a single red flower. [fixed in 1.9-pre1]
 * New biomes are very repetitive overall. It all looks the same in giant areas. [same in 1.9-pre1]
 * Giant areas (even such with very big mountains) do not contain a single tree. [same in 1.9-pre1]
 * Sandy beaches are almost gone. Only very small patches of sand can be found on beaches. [same in 1.9-pre1]
 * Very hard borders between biomes. Even the grass color changes very hard in a few blocks. This makes the borders between individual grass tiles clearly visible. There are no grass color variations inside the biomes. [same in 1.9-pre1]
 * Planks and cobweb in abandoned mineshafts are often generated floating in the air if the mineshaft hits another structure.
 * Abandoned mineshafts often are incredible big and absurd containing stacked mineshafts on top of stacked mineshafts.

I've noticed the hunger bar icons typically start bouncing when your hunger is about to drop. Vincent2128 03:29, 18 September 2011 (UTC)
 * Me too. I think it's the same way that the HP meter bounces a bit when you take damage, the food bar bounces when it starts dropping too. It just looks like it hasn't changed because hunger is probably measured in smaller units than HP (0.1 instead of 0.5 would be my guess, so it takes five mini-units of food loss to see a drop in the meter). --WackoMcGoose 02:24, 19 September 2011 (UTC)

Enderman Bug?
I've added a citation needed tag to the following:

'Endermen sometimes don't attack even when looking directly at them. (E.g. when looking directly at their face).'

It's not really that I feel this claim needs citation, it's just that the wording makes me think that this isn't a bug at all, and that the user has misunderstood endermen, assuming that they attack you when you look at them, rather than when you look at them and then look away. Does anyone know of a bug that this could be, or should it be removed? --Troagador 19:11, 15 September 2011 (UTC)
 * I think by "attacking" he means "going hostile". I would remove this anyway. I can think of several reasons why an enderman is not going hostile. To far away? Behind glass? Wearing a pumpkin? Was F3 pressed? Texture pack? As long as no reason is listed the sentence that they do not attack "sometimes" is useless. --Mrheat 23:03, 15 September 2011 (UTC)
 * I've updated the wording, though my update might be a bit snarky, so feel free to modify it again. This is a problem on our server, as well. We first throught it was a corrupt game file due to accidentally running craftbukkit built against 1.7.3 between running vanilla 1.8pre and vanilla 1.8beta, but the issue has persisted in a new world that's only run on the vanilla 1.8beta server. When looking at the endermen, they don't stare back. If you do catch them in the face, it might look like they're staring, but they will look away and continue playing with blocks. The only way we've been able to get endermen to go hostile is to first attack them. We did not experience this on 1.8pre.


 * If necessary, I can make a twitter post and link that as a "citation". I don't know of anywhere official to file bug reports for Mojang to view. If such a place exists, I can file a legitimate bug report and provide the URL to the bug report as a citation. But if that's the requirement to be on the wiki list, every single listed bug requires either a cited bug report or acknowledgement from Mojang. The random "citation needed" marks are absurd. Either everything needs citation or nothing does, otherwise we're a wiki without any real standards. ~Bob/Paul~ 02:15, 16 September 2011 (UTC)

I haven't tested personally, but the consensus seems to be that in SMP you have to aim above the actual enderman for it to become hostile to you Frymaster 23:23, 15 September 2011 (UTC)


 * Confirmed. We just tried. If you target about 3 blocks above the endermen, he becomes hostile. If you move away from that target (such as targeting the enderman himself or anywhere else) he attacks. Will update wiki. 96.18.65.54 04:20, 16 September 2011 (UTC)

Experience bar bug
I died in SMP after having a lot of XP. Then I went to retrieve my items and xp. And my xp bar just disappeared after I picked up all my xp from the ground. Every time I die I get my xp bar back and when I pick up my xp again, it disappears. Screenshot: http://i.imgur.com/oUwHz.png

Odd, when I died in SMP and picked up my exp again this did not happen. Are you using vanilla Minecraft or a texture pack? Vincent2128 03:33, 18 September 2011 (UTC)

Happened to me as well. However, in this case I died twice, and the second time I died while I was still receiving my old experience orbs. After the second death, my experience bar was gone. I even logged out a number of times and switched to the default texture pack, but it didn't work. LTK 70 18:39, 18 September 2011 (UTC)

Armour Destroying Itself Without Taking Damage? - SMP
In SMP, rather weirdly, my armour has started destroying itself though i've taken no damage. After about 2 hours of gameplay my armour dropped from 9.5 icons to 8, and after another 12 hours of non-gameplay (i.e. not being online), upon reconnecting my armour is just one icon. The server I'm playing on has online-mode: false, but there is SecureLogin or Authorize (both plugins) installed and I am sure no one knows my password. Vincent2128 03:29, 18 September 2011 (UTC)

1.8.* Bug, or intended?
In 1.7, the version text ("Minecraft Beta 1.*.*") was removed from the main in-game screen, so it was only visible in the debug text and the main menu. In 1.8, it's back. I used to think removing it was a bug, but then I got used to it, and having it back is actually kind of annoying for recording machinima. The reason I think it's a bug is that I know Notch changed the text location on the main menu, so maybe that change accidentally re-added it to in-game. Anyone else know about this? --WackoMcGoose 02:30, 19 September 2011 (UTC)


 * I thought it was vice versa: it wasn't meant to let the text hide. I mean, it was used to be there... --Lulloman 14:06, 26 September 2011 (UTC)

crash near bedrock
I couldn't find this on either the main page or the discussion page, but I'm getting crashes each time I approach or move away from the bedrock layers (saves then blackscreens). It seems to be an SSP only problem, as I've not encountered any crashes when going near or away from the bedrock layers on any servers. It's been happening on worlds both generated before and with 1.8 and a world generated in the 1.8 prerelease. --81.104.81.41 12:58, 19 September 2011 (UTC)


 * Can not replicate. Are you sure that it isn't usual "Java runs out of memory" thing? — MiiNiPaaT 13:03, 19 September 2011 (UTC)

I can start up Minecraft fresh, load a world and take one step down (or up) and get the crash. I'm not sure it's related to memory unless something near the bedrock is taking up a lot of memory. Checking with the F3 stats toggled on it's only using 10% of the allocated 512mb; though looking at the error logs I'm seeing a lot of similar errors caused by OpenAL32.dll --81.104.81.41 19:10, 19 September 2011 (UTC)

Chests turning black? and my hand
In creative mode in 1.8 whenever i look at chests (any direction) it turns black. when i look down with an empty hand its also black. what is this? oh, and when i hold a chest, its black NO MATTER WHAT. what is this and can i fix it?

I found this bug in SSP too. More items are affected by this too.

This is just a lighting problem of the new lighting system... but Notch will fix this, no doubt! --Lulloman 14:08, 26 September 2011 (UTC)

I feel like this problem is only for me... I watch people upload minecraft videos and its fine for them, but for me; My chests are turning black, my hand is flashing and signs are turning black. I cant read what I've wrote unless i go in some weird angle.

Note about pushing minecarts east/west
As an added note on the pushing of minecarts east/west, the bug is not present if the X coordinate is greater than -2 and less than 2. This is probably useless to most players though. --Cablemonkey42 22:34, 19 September 2011 (UTC)
 * Did you test this with or without some rails going north and south? If it was with rails north and south, the minecart had already enough speed for travelling 4x without the powered minecart.--Lulloman 14:12, 26 September 2011 (UTC)

Lava, TNT and Water bug
Just wanted to share this here before I added it to known bugs, not sure if its a problem I am having or everyone is having.

I have noticed a bug listed that TNT is transparent again in 1.8 I do NOT have this problem..are we sure of this?

If you place a tower of TNT on one block. Then use inventory hacking to obtain lava and pour it from the top, it will not ignite any of the TNT blocks in the tower. It will continue to cover all sides, then will pour around the edges at the bottom. The lava occupies the block where fire is and cannot burn. This is also displayed with trees, but not wool, due to it's tendency to start burning quicker. Picture: http://i.imgur.com/oPoGm.jpg

Also, I have noticed that lava will continue to go into water and not form cobble stone or obsidian after being placed above the water. It will pour down towards it and then continue to pour under the water. You will see that the cobble stone or obsidian is created at the top/bottom of the body of water.. but not at the top where it should be done. Also you can notice in the the picture, its almost as if the water/lava are fighting to show through each other.. Picture: http://i.imgur.com/DzFGN.jpg Anthrophobic 01:14, 20 September 2011 (UTC)


 * The second issues seems to have been cleared up since the 1.9 pre-release. Although I have not tested the first issues yet.
 * Yes 1.9 pre-release 1/2 both confirm the second issue has been fixed. --Throex 15:33, 29 September 2011 (UTC)

Nether Bug
Not sure if this is a problem for anyone else out there, but... When I go to the Nether in SMP I continue to get "Connection Lost", I attempt to reload the game and the nether will load for a few moments, then it continues to give me "Connection Lost". Is this a bug? Or possibly a problem from my connection or the server? Note: There are only 2 people on the server.

Anthrophobic 01:21, 20 September 2011 (UTC)

I'm not sure if this is the right category or the right place within the category to put this, but here it is. I was wandering around in the nether and ended up getting into a fight with 4 ghasts, and by fight, I mean I was running around deflecting their fireballs without firing arrows back. Anyways, I ended up getting kind of hurt (down to 2 hearts of health), and it didn't look so good. Then, the game just slowed down a lot. I mean, at first I thought that the game had stopped, but it was simply incredibly slow. And it wasn't jerky at all when it slowed down, it was very sinuous. I kept moving and the speed slowly picked up again, but like when it slowed down, it was very smooth. I'm very sure this wasn't just the game lagging on me, because I've had that happen to me before, and this was just totally different, and felt almost intentional. So, I was wondering whether that was the game glitching on me, or whether that is simply some feature when you get very close to dying.

Guard Stance build-up bug
In Single Player, when taking the "Guard stance" by right-clicking with a sword out, any consequent left-clicks are built up until you release the right-click button. To clarify, hold right-click, face away from a door and click the left-click a few times, then face a door and let go of right-click- the door will make a sound like it was opened and closed as many times as you left-clicked, and if your number of left-clicks was an odd number, the door's state will toggle (open to close, or vice versa). If anyone else can test this and confirm it, I would like to see it on the list of bugs, because I doubt it was intentional. GraklingHunter 21:02, 21 September 2011 (UTC)


 * I tested it with a wooden sword and it works. It doesn't work against mobs, but the sword will lose durability equal to the number of clicks. Zahami 20:57, 25 September 2011 (UTC)


 * I also tested it, when aiming at a mob and while in a guard stance you left-click 5 times, the sword loses 5 uses after you release the right-click button, but also deals the damage of 5 uses, but only if you would have hit the mob 5 times. Also I've seen that you can destroy blocks when in Guard Stance, without an animation.--Lulloman 08:56, 26 September 2011 (UTC)

Hostile mobs do not spawn in the Mushroom Biome?
I've wandered around for a good long while and haven't seen anything other than Mooshrooms. (Seed: 5630765669477878057, x:-50, z:300)

Also, this biome is connected to the mainland, so the caption on this wiki's Biome page appears to be incorrect.

Hatch/Piston Bug
Picture for reference: http://imgur.com/zs31L If you do a simple set up like I have in the picture. When each piston extends, it will move the hatch over to the open spot and vise/versa. Pretty sure this is a bug, a hatch should be stuck in its place, not move from spot to spot because a piston pushes a block in the way. If anything it should at least pop off the block.

Linux -- input gets "stuck"
Often a key gets "stuck" and you keep moving in a certain direction after releasing the key.

It seems like this issue is related to a bug in the version of LWJGL shipped with Minecraft. Latest versions of LWJGL don't show this issue.

It could be fixed by shipping a newer version of LWJGL, or shipping both the old and the new and using the newer when running in Linux.

Stone Brick Stairs rendered incorrectly
Stone brick stairs display a black border above the "step" faces, where the normal cube block would be: the "step" area of the stair is filled with a semi-transparent black "fog". --Asterix99 06:28, 16 October 2011 (UTC)

Page clean-up request
Some of the formatting and wording of the entries on this page is inconsistent, and some are actually unreadable. I'll be able to fix some of this (already am, in fact) but I could use some help. Otherwise, no actual bugs to report. --King Starscream 21:36, 26 September 2011 (UTC)


 * --Lulloman 19:53, 28 September 2011 (UTC)I can help. Here are some false bugs:

SSP and SMP: (tested in SSP, not true) SSP
 * you can eat food you are holding at the same time as destroying blocks (not a bug)
 * Takes long time to load (differs on certain computers)
 * Players stuck in walls (or whose lower-half is in solid block) will slide towards the nearest gap; however, if the player moves against this force, he will repeatedly slide to .21 and then walk back to .11. The player will not slide beyond .3 to be completely out of the wall. (this is just a fact, not a bug)
 * No mobs spawning when you enter a seed (not true)
 * All Blocks gives off particles (not true)
 * Large sections of "floating blocks" have been generated on new worlds for some clients [5] from a world in 1.5_01. The error only seems to appear in coastal areas in a large scale, floating blocks include: dirt, leaves and logs so far with select ores. Snow blocks seem also to appear on water. (fixed bug)
 * Mushrooms can spawn on leaves of trees. (tested it, haven't seen it.)
 * Since 1.9 Pre-Release, swamps and 'regular areas' cross in a bugged way. - http://i.imgur.com/DX6wG.jpg and http://i.imgur.com/a6dZ4.jpg
 * Rivers can generate through swamps, giving the water an uneven color.
 * Gold Nuggets in 1.9 Pre-Release don't have a name tag in the Item Selection Screen. - http://i.imgur.com/XncFu.png
 * In 3rd person view, putting the camera in the water causes under water overlay not to show, making blocks light up. (not a bug)
 * In 3rd person view, when in water and camera is out of water the under water overlay is still on. (not a bug)
 * You can break blocks while laying on a bed (not true)
 * It seems that since the 1.8 update that minecarts are harder to break: you need to left click the whole time instead of just hold the left click button. (not a bug, just a new gameplay-style)
 * When opened, lit furnaces are brighter than a furnace not open. (not true)
 * When furnace finishes smelting and the furnace burns out all items are lost. (double report)
 * When melting a block of ice by putting fire under it, the water will also not flow and thus not extinguish the fire. The player can then stand in the water and fire at the same time and will be able to drown and burn at the same time. (double report)
 * Monsters spawn in your house or dungeon, even when it's lit. (double report)
 * Creepers may spawn in open areas with torchlight. (double report)
 * Enderman become hostile within a certain amount of blocks not looking at them.
 * Skeletons' fired arrows originate from a block above their body. (tested, not true)
 * If the player is chased by mobs and makes a lot of curves, a mob may move in a wrong direction for a very short time. (true, but… I can’t call it a bug.)
 * In the 1.9 Pre-release the new snow man/golem doesn't create a snow trail in the mushroom biome.
 * Also in the 1.9 PR when creating a snow golem in the mushroom biome, it kills the grass and leaves a patch of dirt behind.
 * In the 1.9 Pre-release, shearing a Mooshroom on a server will cause the regular cow to be duplicated. The extra one can only be seen on the client side.
 * Portals are generated rotated 90 degrees from the portal entered. (not a bug)
 * Torches placed under water will break, but the area will stay lighted. (double report)
 * The player can hit a torch placed on a wall directly behind because the hitbox is slightly larger that the closest distance the player can get to the wall. This bug occurs since Beta 1.6. (new gameplay)
 * Water in a Desert in 1.9 may freeze and become ice.
 * It seems as if the water source mechanics do not always work in 1.8 (tested in SSP, not a bug)
 * When in water in a boat in 1.8 the unending horizon flashes may cause seizures / migraine. (double report)
 * Cannot take a screenshot when the window is maximized. (depends on computer)


 * If Minecraft runs out of memory, it will show this error screen: (not a bug)
 * 1.9 Pre-release there is a chance that you will spawn in lava.
 * In 1.9 prerelease, when equipping full armor that has no damage, the armor bar only goes to 7.5. (The armor pieces sum is 7.5, so I think the problem is armor+ value.)
 * There's a file called map.txt in the achievement folder inside minecraft.jar that causes performance issues. Removing it may greatly increase your performance, but may reset your achievements. (not a bug)
 * Occasionally, the player will wake when it is still night - sometimes spawning an enemy next to them. (not true)
 * Furnaces emit light even if its face side is blocked. The block itself emits the light, rather than the front face (not a bug)
 * If inside furnace inventory Minecraft, Saving Chunks will appear and Minecraft will crash. (not true)
 * when the furnace finishes smelting all items in it will disapear, includeing remaining fuel and finished items. (unclear, double report)
 * If Glass Pane placed near Leaves, it attaches to them. (not a bug)
 * If you allow sand or gravel to fall on you, after moving around it is possible to be in such a position that you will not suffocate and you will be able to see through the sand or gravel and any blocks connected to the sand or gravel. This can reveal caverns and empty spaces. (This doesn't really work as of Beta 1.6, and is completely fixed since 1.8). (fixed)
 * When in third person mode, if the camera appears to be above the water but the player's head is in the water, the GUI will still be darkened. (double report, not a bug)
 * Sometimes while viewing a map the game will switch to a "saving chunks screen" then end on a black screen. (unclear)
 * When sitting in a minecart, every mob you hit will be seen as a critical hit. (double report)
 * You can hit and do damage to any Mobs more than 1 block distance away from them. (not a bug)
 * Right clicking Mooshrooms in 1.9 pre release with a stack of bowls yields one bowl of mushroom soup and the rest of the empty bowls disappear from inventory.
 * If you plant a mushroom in dirt while in Nether and use Bonemeal on it, the mushroom will not turn into a big mushroom, but the hit detection for the big mushroom is still there. Black outline blocks appear where the large mushroom should be but it does not appear. The original small mushroom will remain but it's block will be the black bordered block of the base of the large mushroom.
 * When hitting a Painting, whilst sprinting causes duplication. (double report)
 * Being killed in the Nether will cause though you had teleported back from the location at which you died normally. (not true)
 * Dying while in the Nether will also ignore a changed spawn point (via sleeping). (not true)
 * In SMP (And SP, maybe?) Rain can go through any a wooden house or glass, for some reason. (looks obviously false to me, but unconfirmed)
 * Occasionally, when walking off of a redstone repeater in a room with a ceiling height of 2, you fall through the floor into the block down and next to the repeater. (double report)
 * When wooden slabs are mined, the stone mining sound is played. (double report)
 * If a slab is placed on ice, it still has the "slippery" effect. (double report)
 * Beds cannot be placed on snow. (double report)
 * Stone Stairs have a lighting glitch where the 1/4 wall visible adjacent to the stair will be dark regardless of lighting. This does not appear to happen with any other type of stairs. (double report)
 * Stone Brick Stairs can drop Cracked Stone Brick and Mossy Stone Brick when destroyed due to translation of block data to damage value.(double report)
 * Axes do not break certain wooden blocks faster than hands, like you would expect. These blocks include wooden stairs, fences, wooden doors, signs, crafting tables and jukeboxes. You can break blocks faster, try it punching stone! (double report)
 * When in third person and underwater, the view will be darkened even if the apparent camera position is above water. And vice versa (you being above water, camera being below).(double report, not true)
 * Lily pads phase through boats
 * Water in Desert biomes may turn to ice despite being in the Desert.
 * Walking while shooting a Bow at lowest charge (especially angled slightly downward) can cause the player to injure himself.(not a bug)
 * If you save during rain and load later, you won't hear the rain's ambience sound. (not true)
 * Rain goes through Wooden Planks. (not true)

SMP


 * If a player is killed by an arrow from a dispenser, the server will crash with a NullPointerException. (not confirmed, but looks false to me)
 * Occasionally, the level.dat file is re-written, causing Minecraft to generate a new spawn. Also occurs in SSP. (double report)
 * Upon being teleported with /tp, chunks will load in order from closest to farthest from the point the player has been teleported from. This results in the world appearing very slowly and glitchy for a while, especially on slower servers. (Is this actually a bug?) (not a bug)
 * If a player stands one block down and to the side from a portal and uses a crafting bench, putting an item into the 3*3 crafting square, they can then wait for between a minute and two minutes, and the portal will bring them to the Nether despite the fact that they are not technically in the portal. This causes the item in the crafting square to duplicate, as well as possibly turning it into a very glitchy item which, after dropped, can be picked up any number of times, appearing in the player's inventory but not disappearing from the ground. (double report)
 * Chests are black and unlighted until opened. (double report)
 * A right-hinged door (when looking from the outside) will act as though there is no door present and as a result, you will be attacked while trying to go to sleep. (double report)

 * When a lily pad is destroyed, the player may pick it up, but its color changes to gray and it cannot be placed.
 * Powered minecarts do not push other carts east-west (double report)
 * If a mob spawner is placed on grass, it will spawn client-side ghost pigs that cannot be killed. (3rd party software bug)
 * Squid moving on the bottom of a body of water make the normal "footstep" sound. (double report)
 * Redstone Repeaters occasionally become locked if their chunk becomes inactive while they are in their powered state. (double report)
 * TNT doesn't make the fuse sound in SMP when activated. (double report)
 * It is possible to stay underwater without drowning using a bucket. Right-clicking on the right water block with an empty bucket creates an air block for a short time which is sufficient to reload the breath meter, thus it is not easy to hit this right block. (double report, not a bug)

CSP


 * When flying too high, all air blocks below a certain height are changed to water. (not true, it's the void)
 * It's possible to hit village npcs through blocks and the block won't break (1.9)
 * You can hit mobs with a sword from huge distances. Unfortunately, this bug can't be abused for the achievement for killing a skeleton at a distance of 50 metres. (not a bug)
 * 650 total bugs (random statement)

Resort/Redo?
Known Bugs is getting to be a hassle to even come to and read. Is there anyway we could take the time to go through and sort these bugs out? Maybe include bugs that are not comfirmed to another list called Known_Bugs_Unconfirmed or something. Maybe sort the bugs out into versions? 1.1 bugs still in the game, 1.2 bugs still in the game etc.. Just thought that since the version history was not a bad idea, this would help out as well? --Throex 17:23, 4 October 2011 (UTC)
 * I thought more about a major bug page and a minor bug page. It's easier to know the major bugs, which contains common found bugs and crash bugs, earlier than the minor bugs, which contains the uncommon bugs and bugs when you have to do this, this, this, ... to let that happen. Shouldn't that be a better idea?

map changing index not in 1.8.1
Tried to replicate map changing index by destroying a block while holding map (using version 1.8.1 ssp). Could not replicate. Can anyone confirm this?
 * Tested in CSP and SSP, and wasn't able to replicate it. Let's delete!--Lulloman 14:31, 12 October 2011 (UTC)

Spawn change and mineshaft in 1.7?
I found this out when I was messing around with SSP in an old world. I went so far away from my house(I was looking for dungeons under ground) that I saw a mineshaft.I looked at my compass and it said my spawn was the other way from where I was coming.

Edit* To the creator of this post... Please use better grammar and punctuation. If this was 1.8 in a 1.7 world, a mineshaft can be created within new chunks. I have fixed the errors, though please do research before having a crudely worded rant on a formal topic.

"Haunted house" bug
I was playing SMP and i built a house, couple minecraft days later it started spawning lots of hostile mobs next to my door. First it spawned couple creepers and every night more. Then it spawned more than 15 creepers and spiders once and finally started spawning giants.

Possible solution to: no audio at start
Sometimes when I start up I have no sound. It seems completely random and if I restart the game it often goes away. I think I have a solution to this problem. One program I used once told me not to move my window or change windows while it was loading, or it could cause errors. I think That is why Minecraft sometimes loads with no sound. I tried this a few times and it seemed to work, although I don't understand why this may be.

Creative mode boat bug
When you place down a boat in single player creative mode it removes the boat from your inventory as though it were not an infinite stack. Somewen 17:37, 16 October 2011 (UTC)

Bug Labels/Icons Question (NOT A BUG)
Hey there. I have a question that isn't related to game bugs, but rather, the "known bugs" listings here at the wiki. Basically, I was wondering why you guys are using text icons beside the bugs on the lists rather than graphical icons. Is this so it's easy to use the Find feature on each page? Or just did no one think about using graphical icons instead of text? A nice little 16 x 16 icon next to each bug might be a bit more eye-catching, in my opinion. ~ <font face="FixedSys, Courier New" color="#008000">Doc Lithius (Info|Chat|Edits) 17:34, 15 October 2011 (UTC)

Lava Lake in Ocean?

 * Water and Lava lakes can be generated inside frozen oceans

When I came across this bug I had to ask: does anyone have some pictures of this? I've seen lakes spawn in oceans, but not lava lakes. Thanks! - 137.112.116.71 06:55, 20 October 2011 (UTC)

Lighting glitch in stronghold
The upper corners on the left and right when you enter the stronghold portal room will be glitched. Never had this happen i before 1.9 pre 5. Couldn't replicate it, but it is still worth noting that it can occur. Upon further testing it seems like it can also happen with the iron bars in the portal room.

Fence gates does not react to redstone
I think fence gates should be able to get opened by redstone like doors and hatches. Possible solution: http://www.minecraftforum.net/topic/713532-181fence-gate-redstone-fix/

Can't kill pig's when it's inside tall grass.
It's not possible to kill a pig that is inside tall grass. You need to push it out from the tall grass to kill it. Not tested in SP. Found it in SMP. Bulbasar 05:34, 8 November 2011 (UTC)

Tilled land breaking while sneaking from half blocks.
When you step down from a half block while sneaking you still sometimes break tilled dirt. Korbit 08:55, 12 November 2011 (UTC)

Spawn in lava.
I spawned in lava in hardcore, couldn't give seed. It happened again this time on normal mode SSP. Here is seed. 3957282054334031006
