Biome Triangles

 * The Biome Triangles: "grasscolor.png" and "foliagecolor.png" are ignored when included in texture packs. This is old news.

The grass biome triangles in Minecraft.jar are not used properly when a texture pack is used weather or not that pack includes biome triangles.
 * I got the following weird results from using the painterly texture pack. Problem was that the texture pack didn't support biome coloring properly.  Updating terrain.png solved the following.
 * When using any sort of texture pack, the side of grass blocks is no longer colored by the biome triangle.
 * When using any sort of texture pack, (even on that doesn't include biome triangles), minecraft.jar's biome colors are used differently. For instance if you make the grasscolor.png all purple, the grass looks all purple (top and side) using the default texture pack.  If you use any texture pack, the top will be a muddy brown instead (half way between purple and green?), and the sides are uncolored.

Don't know what the procedure for adding bugs to the list is, so i put it here. --Eleazzaar 12:58, 23 April 2011 (UTC)

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."

1. You generate enough force to counteract the force of it pushing up, so you remain still. Not like it's impossible. 2. How is that a bug? Last I remember wood floats in real life :P

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)

thanks for the awnser.--Taco1945 21:40, 31 March 2011 (UTC)

Save/Load bugs
i was playing minecraft on my laptop and the laptop force shutdown without me saving the game. when i started minecraft again, the save slot for the world read 'empty' but it loaded perfectly when i clicked it. when it loaded, i noticed that all of my inventory was gone, i died, and when i respawned, my spawn moved roughly 500 blocks diagonaly away from where it originally was. any clue the heck my spawn moved? --WallShadow 00:39, 22 November 2010 (UTC)

Merge
Could this not be merged with something? -- Zaneo 21:54, 27 July 2010 (UTC)
 * Why should it be? I asked Quatro before making this page and he said it is ok. --Nunuru 05:48, 31 July 2010 (UTC)

Sound bug?
After the 1.0.14 (July 30th) patch I've been having trouble getting the sound to work. I'm not sure what's wrong but most of the time when I start MC the sound doesn't work at all but at one point the sound started working last night and worked for the rest of the night. I don't know what triggers working sound.
 * Try holding down F3 and then hitting S, that's what works for me. --Aninimouse 15:59, 8 October 2010 (UTC)


 * That happened to me and I had to re-download the software. The reason your sound probably started working is probably because you got an update. either that or your computer was messing up. --Cornpopz 02:50, 30 January 2011 (UTC)

Cacti destroying things
How is that a feature? It doesn't make the slightest sense for blocks that touch the Cacti to be destroyed. We have lava for that. – ultradude25 ( T 13:56, 1 August 2010 (UTC)
 * If we touch cacti, we get hurt. If mobs touch cacti, they get hurt. If items touch cacti, they get "hurt" (destroyed). It's a bit odd, but it makes sense. IChrisI 21:35, 1 August 2010 (UTC)
 * I understand it from a coding point of view, but for realism it's retarded. Please tell me how a block of stone can be destroyed by touching a Cactus? – ultradude25 ( T 06:17, 2 August 2010 (UTC)
 * It gets stuck inside the block where you can't get it (cactus knocks you away), so it may as well be destroyed if you can't get it. --Nahere 16:27, 30 August 2010 (PDT)
 * + I'm not entirely sure this game is centered around a sense of "reality". I mean, stone blocks can float around, trees down fall down when you cut the trunk, and you can pick up lava in a bucket. The cactus "issue", while not necessarily real, IS in keeping with the behaviors surrounding the cactus. MrMatthew 17:49, 7 October 2010 (UTC)

Frozen character
I've had this happen to me maybe four times in Alpha. So far it's only happened when I was digging around in a small space and my character suddenly stopped responding to movement keys. I don't appear to be stuck or anything, it's as if the game stops looking for key presses. Saving and exiting the game works as a fix.

Sluggish mouse
I've noticed that the mouse can pause for a 300ms or so when you haven't looked around (moved the mouse) in a while. After moving the mouse, it becomes smooth again. Can anyone else confirm this and the (Frozen character) bug above? --24.67.88.189 17:41, 2 August 2010 (UTC)

Could it possibly be that you are using a wireless mouse that enters a type of "sleep mode" that reactivates upon continued movement? I know my wireless mouse does that, and there is a bit of "lag" between moving the mouse and it reactivating. --Dessalet 06:16, 21 January 2011 (UTC)

Future block
Look at this: http://www.minecraftforum.net/viewtopic.php?f=17&t=33907

I found why the game crashes in specific areas, could someone edit this in the known bugs page? Skunkie

Chest Bug
"Chests sometimes revert contents to previous configuration. Opening a chest, modifying the content, exiting, then going back in displays the items the chest had when it was first accessed. This causes newly placed items to be lost and removed items to be duplicated."

This is a questionable bug I added. I'm sure it has happened a bunch of times, and I just didn't accidentally drop items. I have rearranged all the blocks in a chest gone out ran to anther chest, come back to put something else in and all the items are back to where they were before. I've also lost a 64 count iron stack from this... Alpha ivan 19:27, 1 October 2010 (UTC)

I have discovered this, and i am exploiting it for my testing world. This happens because your inventory is continuously updated, but blocks, including chests, are only updated upon save. My method for duplicating is - put in chest - save - remove from chest - close window or MC launcher

Then when i open up again i have the item in the chest and the inventory. This way i got a large chest of tracks from 4 bars and a stick. (although it never happens to me during a session) Melzardust 16:22, 11 November 2010 (UTC)
 * "Putting any item(s) in a large chest before quitting, opening it and putting the item(s) into your inventory, then pressing ALT F4 and opening it again will duplicate the item(s)." This bug appears to be fixed, and attempting to reproduce it now may cause you to lose the stack(s) you are trying to duplicate. --Doctor Zuber 00:40, 5 March 2011 (UTC)

Bug discussion
This might need it's own page, or be ignored entirely.


 * Arrows hitting doors can float if the door changes it's open/closed state.
 * Suggested fix? When the door opens the arrow is knocked off. Moving with the door doesn't seem feasible. Alpha ivan 19:27, 1 October 2010 (UTC)


 * Arrows can seem to be floating when hitting fences.
 * No idea how notch would fix this. The fence is a block, the arrow hits the edge of the block, the edge of the block just happens to be transparent. Alpha ivan 19:27, 1 October 2010 (UTC)


 * If there are too many mine carts in a world, the game will crash.
 * Exactly how many?


 * If you go under a water stream your boat will accelerate and rise towards the sky.
 * I think this should be considered a feature now.

More possible bugs
Some possible bugs I've noted:
 * If you save and exit the game while on a layer of glass, when you resume the world you may fall through the glass to whatever is below. (Happened once so far, haven't tried to replicate it).
 * In a winter world, only the top layer of water is frozen. I have not checked to see if any broken ice will re-freeze or not.
 * A related bug: If you dig under the ice and strike water you will get a bugged visual (the ocean water will be invisible, however any water streaming off of that water tile will be visible, leaving an odd missing square appearance).
 * If you stand in a square with a lava square diagonal from it but blocked from adjacent squares you can still get caught on fire (found that one out the hard way clearing some obsidian). IE from a top-down view something like below (with cobblestone being basically anything), you could be considered as hitting the lava if you press into the corner. --Lordebon 17:37, 7 October 2010 (UTC)
 * This only happens to one corner. It's the principle behind water column elevators.  Last paragraph. Jaeil 21:35, 21 November 2010 (CST)

In winter worlds, only exposed water is frozen. It's not a bug. Also, the thing about lava affecting you through corners, the same thing happens with items. Sometimes lava burns items through corners. PurpleKiwi 01:41, 24 October 2010 (CDT)


 * Has anyone looked into the fact that sometimes in SMP we can't remove cobblestone stairs? I've got the new server software (as of the halloween update) Its still a problem.
 * Spawn points can spontaneously change location. I can pull out my compass and face the direction of the spawn and disconnect. Then sometimes when I reconnect The compass points in another direction.--Idiotninja 15:45, 4 November 2010 (UTC)

Furnace broken in SMP?
While it doesn't seem to always be the case, I keep running into furnaces that delete the items I put into it - both the fuel and the item to be smelted, leaving me with nothing at all :/. And, the animation for the furnace continues on indefinitely. Is that something server-specific or are others getting that bug? Squarethoughts 19:10, 3 November 2010 (UTC)


 * We get this issue on my server as well. It seems to happen most if you disconnect/reconnect while something is inside the furnace.  If you disconnect then come back, the items will be gone most of the time.  There's about a 40% (present)/60% (missing) chance that the items will be there for a short window when you first open the furnace.  If you're quick you can pull them out before they disappear.  This is caused by the fact that we get a lag bug where being in the server for 5-20 minutes often produces unplayable lag, placed blocks will disappear then reappear, chat will take 30 seconds to a minute to register after being sent, etc (this is new after the boo update).  We notice the furnace bug usually when disconnecting/reconnecting to fix this lag problem.  Relatedly, furnaces often don't face the correct direction until you try to use them, at which point they suddenly turn to face you. --Neromir 00:00, 4 November 2010 (CDT)


 * I've noticed in SMP that if another player looks into a furnace that a different player set up, it will glitch the furnace and usually completely destroy whatever was smelting/cooking inside. This happens nearly all the time. Redeclipse 22:42, 29 November 2010 (UTC)

Inventory Movement Bug
I've found that if I go into my inventory and press W just a half second later, my character will move in that direction without having to hold the W key. As in, identical to the chest glitch, but with the inventory. Zetal 21:26, 3 November 2010 (UTC)


 * Yup, I use this a lot to walk through long corridors. It happens because Minecraft sees the ButtonDown but not the ButtonUp. (in the programming)--PurpleKiwi 21:58, 3 November 2010 (UTC)

Lever Bug, related to Button Bug (SMP)
I've noticed that if you place levers in a 1x2 corridor (just enough space for you to walk in), the levers will sometimes switch onto the opposite block after they are activated by other players, and will then behave much like the button bug (can't take them off without destroying the mounting block). This seems to be a purely visual bug, as the redstone circuit depending on the levers still seemed to function normally. Seems to be a pretty similar problem to what was happening with doors before the boo update. --Neromir 00:07, 4 November 2010 (CDT)


 * I've noticed the same thing, they tend to turn to a certain direction after activation, same things sometimes happens to torches. To me, redstone wires were no longer activated because of this. -Zion007 14:47, 20 November 2010 (RST)

Requesting confirmation of wheat bug
Can anyone confirm "You get nothing from breaking wheat"? I just harvested my wheat and got 3 seeds and wheat. Until it is confirmed, I will remove it. - Ruan942 04:11, 7 November 2010 (CST)

Keeping this list up to date
Are all of these still applicable to the latest version? gracefool 09:21, 7 November 2010 (UTC)
 * I suppose so. All fixed bugs are constantly removed from the page. --Scykei 10:15, 7 November 2010 (UTC)


 * I've removed one of my bugs that was fixed in this latest SMP update --Idiotninja (didn't sign his comment, signed it for him --norooom)


 * I try to keep it up-to-date, at least the SMP part, but there's so many bugs that I could use your help. :) Noroom 04:57, 9 November 2010 (CST)
 * I see bugs that no longer exsist and non bugs (like the wheat thing in smp) on here. --Natedogith1 20:20, 20 December 2010 (UTC)

Flower and Fire bug
I've noticed that in SMP, when ever and where ever there is a fire and you "plant" a flower on it, you can always place that plant regardless if it is touching the ground.

I.E. A log on fire can have a plant on its side floating in mid-air.

Sometimes the plants falls off and can be retrieved by the player. Can anyone confirm?

Invisible Creepers?
The bug " Blocks in areas of approximately 5x5x5 around the player will randomly disappear / break and you can pick them up again. " seems really related to the invisible mobs bug. I had an invisible creeper blow up next to me, dealing no damage but destroying the ground. Should this bug remain? --Ruan942 15:26, 11 November 2010 (UTC)

Minecart mob bug - Seen in player avatar
I encountered the bug "If a mob is riding a mine cart and 2 (or more) mine carts get stuck in each other, after destroying or moving the carts away from the other carts the mobs will be invisible" in a special way with ME and a sheep being invisible. Superpowers =P Melzardust 13:27, 11 November 2010 (CST)

Using buttons/redstone while in a cart
I've got a button on my server attached to some track down the line. I push it while stopped in the minecart and it doesn't seem like it works. I've been able to replicate the problem quite a few times while sitting in the cart, but every time I use the button while not in the cart, it works normally. Can anyone verify? --Neromir 20:25, 11 November 2010 (UTC)

Make bigger chests that 1x2
As for the reed: "Reeds can be placed on blocks that are not grass if placed on a water block" - The same goes for the chests. make a 1x2 chests and then place a water source next to it and place a new chest on the water source. You will then have a 1x3 chest.v--Dr. Weir 21:25, 11 November 2010 (UTC)

mac World Select bug not on all systems
The first bug listed for SSP is the Mac OS X World Select bug. I've never had this issue on my Mac, but I've only been playing for a couple of months. Is this an old (and now fixed) bug? Adeilt 22:44, 13 November 2010 (CST)

SSP or Alpha?
I beleive it should be listed as "Alpha" because thats the name most people use. -F1racer101 22:56, 18 November 2010 (UTC)


 * "Alpha" describes SSP and SMP. If you just say "Alpha" there is ambiguity.  Adeilt 02:17, 19 November 2010 (CST)
 * How is this a bug? Oa10712 22:41, 23 November 2010 (UTC)


 * Ummm...its not a bug, and no one said it was a bug. I thought it would be easier to understand the page if it said "Alpha" but Adeilt explained why it wouldn't. -F1racer101 05:14, 24 November 2010 (UTC)


 * So you bring this up on a talk page for game bugs. --SpootKnight 23:10, 23 November 2010 (CST)


 * Well i'm TALKING about the PAGE for KNOWN BUGS, on the KNOWN BUGS TALK PAGE. Where else would I put it? -F1racer101 05:14, 24 November 2010 (UTC)


 * Just so we're all on the same page... on the known bugs page it says SSP. I thought it shouldve said Alpha, but I was wrong. -F1racer101 05:18, 24 November 2010 (UTC)

Invisible Enemies
Well, I had invisible monsters in multiplayer, so I searched the internet and it says the reason for it is that difficulty is set to Peaceful. So, the game just ignores the monsters, almost like it is giving you false comfort. For now the monsters don't do anything, but come tomorrow's update we will have health in SMP, and I personally think it would be hilarious to watch the peaceful people killed by monsters they can't see.--Pizza2004 22:24, 23 November 2010 (UTC)

Boat/minecart bug
If you disconnect in smp while in a boat, it also creates a duplicate you, though when it happened to me I had to disconnect because of bugsNahere 16:42, 24 November 2010 (CST)

Question on some entries.
Hello everybody, I was going through the bug entries and noticed some odd ones: Is this a bug? If I remove the nail on which a painting is hanging, then the painting is sure to come off. Regardless how big it is. You can even see the string on which a painting is going to be attached to a wall in your inventory.
 * If a block is removed from behind a painting, it will pop off the wall when a player touches it after a reload, even if it is a multi-block painting and there are other blocks still behind it.

What does this mnean? Is the track above you while you are riding it or is the minecart on a track?
 * Riding in a minecart on above track may cause your player's image to disappear until you die or reopen Minecraft.

Isn't this what you'd expect the minecart to do? Or did the poster meant that you can pass thorugh a minecart?
 * A player will pass through the minecart, but when the player is passing through it counts as "pushing" the minecart.

Invincibility is gone, do zombie pigmen still not attack?
 * Zombie Pigmen do not attack when hit. This is most likely due to the invincibility glitch.

Metalhannes 18:08, 24 November 2010 (CST)

Crashing then suffocation?
Not sure if this has already been covered, but I couldn't find it anywhere. In SSP I've had the game crash a few times, while I'm destroying large numbers of blocks for quarries or bases. When I load up the map again, all the blocks are back where they were at the last save, but I'm where I was when the game crashed. Since in some cases other blocks were there first, I suffocate. Has anyone else had this? Somnicule 06:11, 26 November 2010 (UTC)

It's entirely possible. Minecraft saves your inventory/origin often, but you have to save the world manually. If the game crashes, your origin would be in the quarry, but the world would revert back to flat ground, thus you end up underground and suffocate. I've had this happen in beta too. --Zkyo 13:33, 31 March 2011 (UTC)

A few more bugs

 * When you place a torch on a tree's leaf block, it does not make a sound, nor does it decrement your inventory. Tested in SMP.
 * Crouching does not prevent hoed ground from being trampled.
 * Mobs spawning on top of trees?
 * Creepers are difficult to kill without exploding, perhaps the distance to diffuse them is off. xkeitarox--Xkeitarox 12:34, 27 November 2010 (CST)

Actually, only the first one is a bug, I think...Sneaking (Crouching) Is SUPPOSED to prevent farmland from being trampled. Mobs CAN spawn on top of trees, if it is set to Fast Mode, rather than Fancy, as on Fancy, the leaves are considered transparent. And Creepers are difficult to kill without exploding because, depending on difficulty, you have to go further to make it recharge. Stinkbug22 16:44, 27 March 2011 (UTC)

Crouching does prevent crops from being trampled. I'm not sure about farmland though. The mobs spawn on trees because on fast graphics, the leaves count as opaque blocks. In SMP graphics are set to fast in the server, even if the clients have it set to fancy, thus mobs will spawn on top of transparent leaves in smp. As for the creepers, the distance does change on different difficulties. Also, they sometimes explode if you are far enough away. This is due to lag. A problem i often have when fighting creepers in smp: they hiss, i back away far enough, the counter resets. Even after 10 seconds or so, they explode instantly once in range, without a countdown. Also, they sometimes explode completely randomly, even if i'm 8+ blocks away. It's rather annoying, i once had a creeper blow up my front door while i was on the other side of my house, on an empty server. --Zkyo 13:42, 31 March 2011 (UTC)

Minecart duplication
One of the bugs about the duplicating minecarts from a cannon needs to be updated: --Lanky ninja 07:32, 1 December 2010 (UTC)
 * You don't have to be in it
 * it sometimes works with 1 TNT
 * and it works in current version

Strangely, i've never gotten any drops from a minecart tnt cannon. Maybe it was from lag, and the cart drop got blown up too, idk. --Zkyo 13:43, 31 March 2011 (UTC)

cactus placed next to smooth stone
I have noticed that you can place an cactus next to smooth stone in water, probably this is caused at same bug by reeds. Ferry 19:48, 13 December 2010 (UTC)


 * I just did something similar to this [I haven't tested ^this though]; I put a Cactus on a sand, and to 3 of the sides of the Cactus, are more sand blocks, and to one side is water. The cactus is not breaking, and it is just sitting there. --DwarfWoot 05:19, 12 February 2011 (UTC)

It's a bug. You can place cactuses almost anywhere in water, even with blocks on all 4 sides. As soon as a nearby block is updated, or the cactus grows, it pops out. --Zkyo 13:45, 31 March 2011 (UTC)

Fullscreen/Windowed inventory glitch
When I toggle from full screen to windowed mode, I am no longer able to use the mouse cursor to click on things, such as items in inventories or buttons in the menu. Pressing keys, aiming, and clicking the mouse work fine. It's only the cursor that has the problem. When I return to full screen, it's fine. I suspect the issue is that the game thinks my mouse cursor is far off screen to the left, because my avatar in the inventory screen stares off to the left, regardless of how I move the mouse. He still looks up and down with my mouse, however. --Kuilk 17:55, 20 December 2010 (CST)
 * This is most likely a problem with the MouseMotion listener in Java, seeing as it only has an effect on the position of the mouse. Fright01  × 18:33, 28 January 2011 (UTC)


 * I find this bug rather irritating. I get a 10 fps increase in fullscreen mode, and i also tend to get alot of IM messages. If i switch away to answer several, its annoying that i can't use the menus in windowed mode anymore. --Zkyo 13:48, 31 March 2011 (UTC)

Tooltip misspelling (beta)
When you hover the curser over netherstone it comes up with netherack, i assume it's supposed to say netherock.

-- Lanky ninja 20:18, 20 December 2010 (CST)
 * It has been confirmed that netherrack is the correct spelling. Zephyriphoenix 16:23, 15 January 2011 (UTC)

Doors and cacti
I am using version 1.2.1_01 (Halloween update), and when reproducing the glitch related to doors and cacti, the doors I get are always collectable. For example, I could place a door between two tall cacti and that would get me two collectable doors. Hell, I got 8 doors from one this way. Also, doing this with tall cacti seems to destroy all the cactus blocks but one. --Mega-Mario 16:42, 21 December 2010 (UTC)


 * Confirmed bug. I actually use this as a door farm when i make door traps. :D --Zkyo 13:50, 31 March 2011 (UTC)

Various SMP bugs

 * Ambiance sounds do not play in SMP.
 * Sometimes, the horizon will render as a single terrain pattern repeated endlessly, and will change shape by walking towards it. I have only seen it happen on SMP, and only since Beta.
 * The collision reach for mobs seems much, much longer in SMP.
 * Rapidly throwing Eggs in SMP will cause the client to crash.
 * Monster Spawners have no fire effects in SMP.
 * When a pickaxe breaks at the same time as you destroy a block, you can't collect the destroyed block if it can't be collected barehanded.


 * That last one irritates the crap out of me. You don't know how many times i've lost diamonds/redstone to that glitch. D:
 * It only occurs in SMP, at least thats what i've noticed. --Zkyo 13:52, 31 March 2011 (UTC)

More stuff

 * Seems like mob spawners are entirely fixed, not sure about SMP tho.
 * When placing a TNT next to an active redstone wire, so that the TNT is connected to the wire, it does not detonate.
 * "If you place dirt under bedrock, till the dirt then place the seeds, the bedrock disappears." -> This can be reproduced with any block (not just bedrock). And it can also be reproduced in SMP.

WARP SPEED bug
"Start a new world, then set your clock to one hour ahead. WATCH THE GAME COMPENSATE." Is this a valid bug? Toomai Glittershine 15:29, 19 January 2011 (UTC)

Debatable. Minecraft uses your system clock as a reference for time (early speedhacks made your system clock go faster). I'd say it's not really a bug, more as a glitch that shouldn't happen in the first place (who just randomly changes their clock ahead? exceptions being DST) Sparx 04:51, 22 January 2011 (UTC)

I've actually gotten this glitch for a small moment without tampering with any clock at all. Hmm, weird? I was mining a single tree branch at the time. Codyfun123 02:41, 8 April 2011 (UTC)

I've had the warp speed glitch happen to me as well without editing my clock. I was just mining smooth stone at the time (it might have been some ore) very useful glitch for what i was doing at the time but it slowly went away as i moved any direction but forward (I don't remember if looking and moving forward did the same thing or not.) Just a little bit of what i went through --Lazeman 08:01, 16 April 2011 (UTC)

Screenshot Crash
I tried Sneaking (Shift), and then using F2 to take a Screenshot, and the game froze, causing me to need to kill the process. (Windows 7, Single Player) I was also at the Highest block level, if that makes any difference.

Also, not related to this, but related to screen shots; I stretched the window the have more horizontal sight, and was then unable to take a screen shot, instead getting an error message where it normal says "Saved blah blah blah" --DwarfWoot 15:19, 25 January 2011 (UTC)
 * Holy shit, that's quite a nasty bug. Trippy, but mostly nasty. The 3D warped and rotated violently for me. Windows 7, SP. Good catch, wonder if this is reported on GetSatisfaction.. Also confirmed the other bug. Will add, cheers. --Gnu32 16:20, 25 January 2011 (UTC)
 * That's interesting, I tried the second bug again and it's just not coming up... will investigate further before adding to the list. --Gnu32 16:25, 25 January 2011 (UTC)


 * Give it time. Minimize the window, it'll take the screenshot. It's a 1.8 GB .tga file, and you need a huge amount of ram to get it to work. http://www.reddit.com/r/Minecraft/comments/f6oro/running_12_02_better_not_press_shiftf2/c1dovqx
 * Notch commented on the feature on his twitter http://twitter.com/#!/notch/statuses/28553723806490624 Thevdude 17:13, 25 January 2011 (UTC)
 * Holy bejezus, confirmed this with a 348MB file sitting in my screenshots folder. My bad, bro, cheers for linking this. --Gnu32 17:21, 25 January 2011 (UTC)
 * Sorry for not mentioning the .tga file, I did see it, but wasn't sure at the time what the .tga was (I figured that it was some sort of an error). Also, I have x64 bit with 8GBs RAM, plus a ReadyBoost dedicated 8GB FlashDrive, and I can't overcome either errors. Maybe I'm not waiting long enough for the crazyness to go away? I tried waiting for about a minute or two before ending the game. And yeah, thanks for explaining/links. --DwarfWoot 17:56, 25 January 2011 (UTC)
 * In the Twitter post, it sounds like it is not supposed to do that ("I just realized" sounds like bug discovery to me), leading me to interpretate it as Shift+F2 is in-fact a bug, caused by said "Half-finished huge screenshot test code", and that the feature is not supposed to be there at all yet. With this thinking, it seems like it should be listed as a bug, with possibly a link to the Twitter (if only to warn others until the real version of Huge SSs are implemented). --DwarfWoot 18:03, 25 January 2011 (UTC)
 * When I get home tonight, I'll see how long it takes. Definitely more than 2 minutes, but I've only got 2GB ram until tax return. Apparently irfanview and gimp will open them. Photoshop will toss an error. If you watch the screen go weird, you'll see it's zooming in on various spots of the screenshots (it seems like). I just went to something else (the game will continue when it's done) and made a sandwich. After a while, I clicked back on it and it was done. I didn't get a chance to open my image, though. Thevdude 18:46, 25 January 2011 (UTC)
 * So it's not a bug? Call me a fool (for i am one) but if something doesn't run the way it's supposed to, im pretty sure that is a bug, otherwise, i want an explanation as to why it's considered a "feature" and not a "bug". Dessalet 06:42, 2 February 2011 (UTC)
 * I still think it's a bug, because the undocumented huge screenshot feature uses the same keybind as making a screenshot while sneaking..  The fact that there is a undocumented feature to make large screenshots is ok, even if it crashes minecraft on most computers.  But it's still conflicting with making screenshots while sneaking :S Lalophobia 10:36, 26 April 2011 (UTC)
 * Well it _was_ a bug apparently, because it seems to be fixed ;) Does anyone know the new keybind for the large screenshot, it's not shift f2 any more :) Lalophobia 14:38, 27 April 2011 (UTC)

Mouse Windowed bug
I never mentioned this because I figured that it would have been pointed out by now, but It isn't. When in Windowed mode, when the player has the mouse visible (Menu, Inventory, etc.), if the mouse is taken away from the game and then brought back, the mouse will take on the appearance it last had outside of the game (So, if entering from the sides of the game, the mouse will be Left-Right Resize arrows, etc.). Not a game hindering bug, as the mouse if still fully functioning, however it is clearly a bug, and visually annoying. This is fixed by exiting the current screen (Menu, Inventory, etc.). (I saw the When Exiting Fullscreen bug, but this is not the same thing) --DwarfWoot 18:17, 25 January 2011 (UTC)
 * I hate this one so much. I'm always all "YEAH, THAT'S HOW I MAKE THAT STUFF!" and I go back to minecraft and have little up and down resize arrows. IDK what causes or how to fix that one, though. Thevdude 19:01, 25 January 2011 (UTC)
 * So you agree that it is a bug then? I don't see why it wasn't added to this list a long time ago lol. As far as fixing it goes, the quick fix is of course, closing the current object (In game Menu, Inventory, etc.), but as far as a real fix, I had suggested a few weeks ago in the forums that the game implements its own cursor (like a Pixeled Cursor, that matches the MineCraft look), because as long as the Windows mouse is hidden, there is no issue. --DwarfWoot 20:49, 25 January 2011 (UTC)

Wool Bug
I just noticed that when holding multiple colors of Wool (Have 2+ different colors by one another on the HotSpots) if you switch from one wool to another, then the color of the one you are holding changes to that color before the player physically switches the items. (If my explanation didn't make sense, try switching between Wool and Cobble, then try mine, and you should more clearly see what I am referring to). I first noticed this when playing InBrowser Beta, as it is a fraction slower, then tested it again on the .exe Single Player. --DwarfWoot 21:26, 25 January 2011 (UTC)

Another bug with wool, you can't use bonemeal to craft white wool blocks, unless you START with a white wool block. You have to use it BEFORE you punch the sheep to get white wool from any other color (light grey and such) wool. --Thevdude 15:48, 26 January 2011 (UTC)
 * Of course. As you can not get a red wool starting with a blue wool… – Scaler (t) 15:55, 26 January 2011 (UTC)
 * You can dye a blue sheep white with the bonemeal, however. Bonemeal is the most useless dye! Thevdude 17:16, 26 January 2011 (UTC)
 * so the only way to dye wool is to dye the sheep or start with white wool? So the only use for bone meal as a dye would be to make lighter colors or to change a colored sheep back to normal? That seems like a fail.--Cornpopz 02:53, 30 January 2011 (UTC)
 * I think that this is balanced by the fact that Bonemeal is such a great farming item, where as many dyes can do nothing else. --DwarfWoot

Custom Controls
In the article it says that controls revert to normal after updating, but every time I start playing my custom controls are reset. Does anyone else have this problem or am I doing something wrong? --Cornpopz 02:48, 30 January 2011 (UTC)
 * I haven't had this problem in a long time. Try deleting the minecraft.jar and the version file, and redownload them by running the minecraft.exe --Thevdude 16:48, 1 February 2011 (UTC)


 * -No, don't delete anything. Just open the client and click the Multiplayer button on the title screen, then try to connect to a server. Any IP address will do, even if it's not real (Just make up a series of numbers). When attempting to connect, a certain file in the coding gets overwritten which causes your controls to reset. After doing this, your custom controls will be preserved when you exit the client. TenhGrey 19:50, 3 February 2011 (UTC)

Umm no, it's because of how the loop-read for the options file is setup. They didn't setup the errorlevel correctly in the loop-read so when no value is detected on that key (lastServer:) it pretty much stops loading the config file there. As you will notice, your custom key bindings are right below this value. You could just edit your Options.txt and put a 0 as the value for that key. If this were an ini file (as it's formatted like), they could index through it as such, and no such problem would occur. The method above would work too, but the reason is not even close to the actual problem. MDR 08:39, 14 February 2011 (UTC)

Walk in/fall through blocks
There are a few ways to walk in/fall through a block that you shouldn't be able to.
 * Break a minecart (boat?) while on a block. You'll fall into the block, or through it if there isn't anything beneath it.
 * Crouch, save and quit, then come back. Same effect as before.
 * (this one is new to me) have a water current push you against a block. Save and quit, then come back. Same effect.

Can anyone verify the last one? --Thevdude 17:21, 1 February 2011 (UTC)

I made several attempts to duplicate the last one on different types of blocks, and none seemed to work. When i tried to move around the block, i couldn't. --AParkedCar 14:55, 1 February 2011 (UTC)


 * Just tried again, isn't happening. There was a torch on the block, maybe that has an effect? --Thevdude 01:23, 2 February 2011 (UTC)


 * The following patch appears to fix the issue when breaking a minecart while riding it. Prior to the patch, if you are riding a minecart and you break it, you fall through to the next block below rather than end up on the track. If there is no block below you will continue to fall and potentially take damage. I've only tested this patch in single player while destroying the cart I am riding. I am posting this here so others may try it out. UsedOnlyTwice 11:50, 31 March 2011 (UTC)

Invisible PC, 3rd person view
It's only a minor cosmetic bug, but when you stand above layer y=128 (maximum height), switching to 3rd person view will render your player character invisible until your head moves below the the top edge of the map. This probably also happens with NPC mobs, but this is untested. TenhGrey 19:44, 3 February 2011 (UTC)

Added a redirect from "List of bugs"
Nothing else to say, just wanted to document it and such. --Megabobster 06:51, 14 February 2011 (UTC)

Fences Fixed?
I believe the bug where you get stuck on top of a fence in smp is fixed, or at least a minecraft rep claims it to be in this getsatisfaction post.  Troagador 18:41, 17 February 2011 (UTC)
 * I haven't had any issues with fences for a while. --Thevdude 00:48, 18 February 2011 (UTC)

About beds

 * Sometimes when you wake up there will be a hostile mob right beside you.

Is this actually a bug? Something tells me that a poorly placed bed is intended to cause this. I'd agree it's as a bug if this occurred somewhere with a safe home though. Alphap 00:56, 23 February 2011 (UTC)
 * Look in the bed topic. It says it is there. --Coupon22 00:57, 23 February 2011 (UTC)

I found a teleport bug, should it go here? Anyway, two people on SMP server, admin and op. Admin gets into a bed in a two block high space, teleports op to him. Op is standing on bed and suffocating, but admin can see op's head apparently in the same bed. How do I sign this anyway? Bobbobbob 06:46, 8 April 2011 (UTC)bobbobbob


 * You can sleep during a thunderstorm, even during the day.

Is that a bug or a feature? Don't storms make it dark enough to spawn monsters during the day? Besides, staying in bed on a rainy day is not exactly unheard of, though usually with a good book. :) -User:Benjaminkc

Duplication Glitch Gone?
I heard that the glitch that allowed you to duplicate items using large chests was fixed/removed in the February 22nd update. Is that true? Superfield 14:38, 23 February 2011 (UTC)

Screen Flickering and Game Deletion
When running in Full-Screen on a computer with no graphics card, then switched to Window-Mode, Minecraft flickers, partially showing hidden caves and lava pits. When switched back to Full-Screen, it continues to flicker. If you then exit to the menu while in Full-Screen, the computer will crash and the game is deleted.

This can be avoided by switching to Window-Mode, pressing ESC for the Pause-Menu, which will Autosave, and closing the tab (or browser window) without quitting Minecraft.

I don't know whether this is a bug, or just the computer crashing, but it has happened twice. -- ClapNZ 04:47, 3 March 2011 (UTC)

RS Torch Edge Triggering Problem
I already made a topic for this on the circuitry discussion page but its probably also appropriate for here too. http://www.minecraftwiki.net/wiki/Talk:Redstone_circuits#Problems_with_Redstone_Torches Jrob 13:56, 19 March 2011 (UTC)

Can some one confirm?
So when I click on something with the compass it teleports me to that spot. I don't think any of my mods do anything with this.CaliCali

No. On SSP. The mods I have are, SPC and To Many Items.CaliCali

Stacking Fishing Rods
Fishing rods are stackable in SMP. When you stack an undamaged rod with a damaged one and then seperate the stack, both rods will have the same damage on them as the damaged rod. I haven't tested any further. –The preceding unsigned comment was added by Death and Taxes (Talk 12:54, 21 March 2011. Please sign your posts with !

If you connect a door to a cactus attached on top of a sand block, the door will split into two doors. possibly used for door farming? please check.

Already confirmed. Calinou 17:54, 23 March 2011 (UTC)

New Mob Glitch?
As of Beta 1.4, I've noticed that mobs no longer look up at you when you're above them. Instead, they look at the ground. (Needs confirmation) Cacti11 05:40, 2 April 2011 (UTC)cacti11

Did happen but I think its fixed :\... New mob glitch for me is the lighting bug...

Ladder bug
I've noticed that if you put water and if you put ladder in the movinf water on the ground, ladder becomes invisible. Like that: * -water source > -water move direction   + -ladder

record exiting jukebox glitch
I don't know if this glitch happens in SP, but in MP when taking the record out of the jukebox, it creates 2 images of it. The original can be picked up, but the other image can not be picked up.
 * Been around forever, and it's already listed on the page. Didn't you bother looking first? – ultradude25 ( T at 06:30, 4 April 2011 (UTC)

Did look but must have missed it. Good to know. Sorry for the duplicate.

Rigorous testing!
I'm going to be testing a lot of bugs, as this page seems to have a few bugs that are no longer present (i.e. the current first one on the list, creating an "error" message whenever the game is closed). Please don't revert if I remove sections. Megabobster 01:39, 6 April 2011 (UTC)

Done with all the SSP bugs, note that I didn't do ANY bugs that were "sometimes", "it is possible", etc. I removed all bugs that were definitely not there (i.e. when you do this, something else ALWAYS happens) and even added a few I found along the way. I also didn't do the OSX bugs for 2 reasons: 1, I don't have a Mac, 2, I'm pretty sure they were also "sometimes". I might do the SMP bugs tomorrow, as I believe those are a bit more important.

Indestructible minecart
I noticed that when i place a minecart on a rail then go a far distance away then turn back the minecart is indestructible(in singleplayer).When i hit them they didnt shake Thien369852 3:56, 10 April 2011 (UTC)


 * Didn't happened to me in Multiplayer, but when a minecart is moving, it needs more bare hands hit to destroy, yes. C ali nou - talk × contribs » 17:25, 10 April 2011 (UTC)


 * Were you in the Far Lands? That is quite possibly a source of a lot of glitches. How far did you go, how long did it take, and how much did you hack to speed up the cart? Darkid 11:04, 11 April 2011 (UTC)


 * I didnt go to Far Lands,I just go a bit far and i go for 20 minutes also i didnt in the cart.I just let it there and I was used boosters Thien369852 12:42, 12 April 2011 (UTC)

Jumping onto ladders?
I cannot jump up to a ladder and proceed to climb it, which was a useful way of dividing floors of my base. Does anybody else have this bug? The ladder is in the block above me, I jump and hold forward. (forgot to add name, and got the time wrong >_<) Kratoyd 17:14, 19 April 2011 (UTC)


 * I don't think that's a bug. It's part of the new 1.5 update. You can only go on ladders if your lower half touches it. It's to prevent the gaps in the ladders people use.It does suck you can't jump up onto it. --Bloodarowman 17:12, 20 April 2011 (UTC)

Grass not growing under certain blocks
I notice that we have the bug about grass not growing under fences and signs, (though grass remains if thy are placed on it,) but what about under doors and sugar cane (the sugar cane actually makes sense, so I'm not sure that part is a bug) are there other blocks that do this? I am playing smp, and I'm not sure if any plugins are affecting stuff, also I havn't been able to get on since 1.5, so if the issue is mine or has been resolved feel free to ignore me. Cultist O 16:53, 20 April 2011 (UTC)

Jeb's Comments
I'm just going to comment on some of these bugs.

General

 * Occasionally, picked up items will not appear in the inventory.
 * This probably only occurs in multi-player, and is an result of the client seeing an item that doesn't actually exist. I would appreciate if people could be more specific on the circumstances of this problem, so we can find it.
 * If you die while viewing your inventory, your character will fall out of the box and will be rotated sideways. The player's skin will also be reverted to default after a few moments.
 * This is not a bug.
 * A bug exists where the game may refuse to remember custom controls after updating (not to a specific version - just updating in general). This is caused by one of the values in Minecraft's "options.txt" file being unset, usually the "lastServer" field - attempting to connect to any multi-player server address (valid or otherwise) typically resolves the problem. 
 * I think this has been fixed.
 * If you place four blocks so that they can stop the flow of water then place water or lava into it you can put a cactus piece into it. 
 * I think this has been fixed, too. Previously there was a special condition for water tiles, which Notch has removed.
 * When Java crashes, your work sometimes cannot be saved and you may have a new respawn point. 
 * Technically this is not a bug, because how should we save the world when the game isn't running? =) Java shouldn't crash, though...

Beds

 * Sneaking does not prevent you from falling off beds, however the player can't walk directly on them as one would stairs
 * Sneaking will only prevent falling heights that are 1 block or taller.
 * Sneaking while sleeping can produce some interesting and varying results, from not being able to see limbs to being able to see yourself and toggle between sneaking and not sneaking. 
 * From Beta 1.5 the game automatically turns off sneaking when you try to sleep in a bed.
 * If you try to activate a bed you are standing on it will not work giving the error message "You can only sleep at night". 
 * If you try to activate a bed when you are too far away it will not work giving the error message "You can only sleep at night". 
 * This has been fixed in Beta 1.5.
 * Beds placed in fully enclosed (on both sides and with only one space above) areas can cause you to wake up inside a wall, killing you and potentially destroying your items. 
 * Technically the bug is that you shouldn't be allowed to sleep there =)

Cactus

 * Cacti cannot be placed next to a portal.
 * This is a behavior more than a bug.

Mobs

 * In The Nether, Ghasts spawn on peaceful, but they would not to do anything. A ghast will disappear soon after appearing. 
 * This should be fixed now.

Paintings

 * Paintings have no player or object collision(players, mobs, and entities can pass through them, and non-solid blocks can share the same position a multi-pane painting is in). 
 * Paintings are not supposed to have object collision.

SMP Beds

 * Trying to get into bed while sneaking disconnects the player(Illegal Stance). 
 * Although the problem is the same, sneaking should be automatically turned off when sleeping in 1.5.

SMP Boats

 * Boats greatly increase server lag. Attempting to move in the boat invokes noticeable delays. 
 * I would like to see more research about this. I don't think it's the boats' fault per se, but rather because players are traveling quickly to unloaded chunks (i.e. causing server lag because more chunks must be generated and/or sent to the client(s)).

SMP Doors

 * When attempting to stack doors, one will be deleted.
 * Not sure if you're still reading this but this means that when you attempt to place a door on top of another door, the topmost door will be lost. Placing doors on other doors is probably not intended, but if this is possible to fix, we could make impressive-looking quadruple doors. LTK 70 19:22, 28 April 2011 (UTC)

SMP Fences

 * Standing on top of fence posts triggers the anti-flying protection.
 * Fixed in Beta 1.5_01

SMP Furnaces

 * Furnaces rotate when they are used. This seems to be influenced by the blocks placed around them. 
 * This should be fixed in Beta 1.5... Can somebody verify it still occurs?

SMP Minecarts

 * Minecarts that pass over pressure plates will sometimes not activate a redstone current, even though a "click" noise is heard. 
 * This will probably never be fixed.

SMP Mobs

 * Every mob will freeze, when the server is timed out.
 * Oh come on! =) A lot of stuff will freeze if the server times out.
 * When slimes divide in SMP they often create many fake duplicates which are invulnerable, and inflict no damage. Disconnecting/Reconnecting causes these fake slimes to disappear. This bug does not occur in Survival (SP) mode. 
 * When slimes divide, they can create larger slimes.
 * These should have been fixed.

SMP Saddles

 * Saddles will return to the player's inventory if the pig de-spawns. This obviously demonstrates that saddles on pigs are not fully server-side. 
 * I think this was fixed in Beta 1.3.

SMP TNT

 * Currently there is a problem that the explosion occurs client-side too, but the effects are reverted by the server-side explosion. This sometimes causes certain blocks to reappear or disappear after the explosion, because the client-side coordinates are not exactly the same as the server-side ones.

Crashes reverting to earlier save
To paraphrase Jeb's words, if Java crashes, you'll certainly lose progress since there's no way for the game to save. There's no way around that. When you say "revert to an older version", how much older are we talking? I assume it's just a few minutes. If you're losing a half hour of building, then it's probably worth attention. --Theothersteve7 15:29, 21 April 2011 (UTC)


 * I mean it will revert to the last time you manually saved the chunks in SSP. I mean when you choose the save and quit option, not just hit esc to save your items/position. I had it crash, and revert back about an hour to when i had saved the day before. That was about 5 days ago. Yesterday, was my server. I have no idea what happened, it never crashed. I just noticed that the spawn had randomly changed, along with the world seed. That happened to me several times on SSP. The chunks saved, but the level.dat file was re-written, so i lost what i was holding, and had a new spawn. As far as I know, the spawn change can be fixed simply by loading a backup of the level.dat file into the server. --Zkyo 15:37, 21 April 2011 (UTC)


 * That's interesting, I was under the impression that the world saved frequently as you went along. Definitely worth being on this page, then.  I would classify the regenerating of level.dat as a separate issue (but certainly an issue).  Now I'm curious how it's handling this. *edit* and I see you already did just that, thanks.  It also occurred to me that maybe the crash caused the file to be corrupt, and so it reverted to a backup instead of destroying your world entirely; at which point I'd say it needs to write changes to that backup while playing if at all possible.  --Theothersteve7 15:46, 21 April 2011 (UTC)


 * I used to think the same thing too. It reguarly does a partial save, most likely to the level.dat. That leaves more options for a write error, causing it to become corrupted. The actual chunks only save manually though. It is possible the crash caused it to be corrupt, but the spawn didn't actually change for a few days after. Plus, there was no crash when my server's spawn changed. now, when I get home, i get to use mcedit and move the spawn for like the 7th time on that server world D: --Zkyo 15:55, 21 April 2011 (UTC)


 * Yeah, I hear you. On the whole, the save system could stand to be more robust.  I hate building an awesome world and discovering the seed has changed partway through.  Ugh. --Theothersteve7 16:01, 21 April 2011 (UTC)

Half Blocks
The other day i generated a snowy world and built my house on the ice. I had to raise the floor up so i used a pathway of half blocks (slabs) to my house and noticed that the slipping effect on ice still occurs on slabs. I haven't tried this since the patch beta 1.5_o1 so it might be fixed now.
 * I can confirm this happens in 1.5_01 too, additionally it happens to the bottom step of stairs on ice. - Alphap T ~ C 02:59, 25 April 2011 (UTC)

Stair visibility bug
I just encountered the stair visibility bug while swimming backwards and making a clumsy bridge of stair blocks while I was fooling around earlier, and it appears that their visibility may not actually be directly linked to proximity to water. It became invisible toward the end, and also onto land. - Alphap T ~ C 02:59, 25 April 2011 (UTC)
 * I believe this was linked to a chunk-based visibility bug. Chunks are 16x16x128, and subdividing them into 8 sections vertically, yielding 16x16x16 sectors, and placing one stair (or fence) in that sector will render it invisible. Darkid 03:31, 25 April 2011 (UTC)

Invisible mobs when dying near spawn point
can someone confirm this bug before I edit the list of invisible mobs? example http://www.youtube.com/watch?v=dUfSZmnO_BU (i had it in SMP) dying near spawn giving invisible mobs Lalophobia 10:18, 26 April 2011 (UTC)

Tree growing with bonemeal: addition
"Using bone meal to quick-grow trees will sometimes cause "floating" trees to grow with the sapling still at the base. Removing the sapling or using more bone meal can cause the tree to grow into an enormous bundle of leaves with no log base. These leaves will now respawn immediately after being harvested."

I wanted to add that if you right click spam the sapling with bonemeal(may take up to 40 or even 50 bonemeal on some occasions) finally a log base will be created, you can use this to force tree spawns in locations they would normally not be able to grow. Also, doing this seems to increase the chances of growing huge trees. This might be caused by multiple trees trying to grow on top of eachother because of bonemeal being added so rapidly.

This was tested on a SMP server by growing a huge forest using admin-created bonemeal and sapling stacks.

list currently split in smp / single player ? what's the place for overall bugs?
This bug list is currently split into single player and multiplayer. Shouldn't there be a 'general' list first? containing for example UI bugs and other overlapping bugs that occur both in single and multiplayer?
 * Other as that, good list ;)

Redstone torches and repeaters in SMP
I noticed redstone toches often get stuck on the off state and every torch placed on that block (even after the block is replaced) will get stuck on the off state when turned off. Redstone repeaters also have a bug like this, but it happens less often. They get stuck on the on state and won't ever turn on when replaced. (I don't remember if I tried to replace the block) Cheeser 15:36, 26 April 2011 (UTC)

I've experienced that problem a lot of times as well Aneesh 18:44, 30 April 2011 (UTC)

Furnaces

Teleporting while in bed
In multiple SMP servers, when I'm in a bed and somehow teleport (whether by tp or by warps), it causes the client to freeze, not showing any response at all. Has anybody else experienced this? Rallias 21:10, 26 April 2011 (UTC)

Someone writing bugs onto the article in first person
Someone editing the article keeps using first-person terms like "I". For example, on the fourth image down the right side, it says "After a forest fire I lit at night". By the way, I can confirm the bug related to the image. Vincent2128 07:42, 27 April 2011 (UTC)


 * It's not of a huge concern. This article is hardly encyclopaedic, if we were going to go for that, it'd probably be easier to just delete this whole thing and start again. It's really just a list of bugs for Notch to look at whenever he's in a bug fixing mood.

But hey, if you feel look going through the article to make it look nicer, knock yourself out! – ultradude25 ( T at 08:02, 27 April 2011 (UTC)

Lightning and Paintings
In my SMP (CraftBukkit) server, I've twice had the server crash due to null reference errors when a painting is damaged by a lightning bolt. Can anyone find out if this also happens in vanilla SMP/SSP as well? --Sukasa 15:18, 27 April 2011 (UTC)

End of Stream
undefined Over half of the servers on SMP are experiencing major End of Stream Errors.

Nether Portal in SMP
It's mentioned in the page on the portal page, but it isn't in the list of known bugs that the nether portal doesn't work at all in SMP. When you light the Obsidian it creates the purple portal texture, and it makes noise like a normal portal. When you walk through it you simply walk through it and come out the other side still in the normal world.

Wallmounted items fall off in outermost chunks
Related to http://getsatisfaction.com/mojang/topics/redstone_torches_disappear_in_smp Observed on MP, goes for anything mounted on walls (Torches, rstorches, signs) Theory: If the outermost loaded/active chunks have items mounted on a wall of a chunk even further out, the item will not have a wall to hang onto, thus fall to the ground. (Because the further out chunk is not loaded/active) This often results in players not noticing until the item has despawned, thus leading to the belief that this is a bug that makes "Torches disappear".

Double doors
Don't know if this is a known bug already, but when you are trying to make double doors by putting rightside door first, it won't "turn around", so when you put the door to leftside, there is two single doors instead of double doors.

I hope my text makes sense. --JurnthReinal 20:32, 27 April 2011 (UTC)--

'Biomes' subtopic
I removed this subtopic because it concerns bugs with worlds generated before the Boo update and are no longer relevant. If Notch is going to reference this list we should keep it up-to-date. I also moved the bug where snow and rain fall through water to the Water subtopic. LTK 70 23:07, 27 April 2011 (UTC)

Fancy/Fast graphics and rain
I just went on Minecraft to play some SMP, and while it was raining outside it didn't give me the (very nice, by the way) sound effect of the rain. When I switched my graphics from Fast to Fancy, the sound started playing again. Fancy to Fast made the sound stop, as if the rain had stopped - even though the rain graphics were still there. I'm submitting this as a bug because the GRAPHICS are set to Fast, not the sound. --NearNihil 13:24, 28 April 2011 (UTC)


 * Yeah, i've noticed that too. My computer can't handle fancy graphics in rain cause of all the particles, but i really like the sounds. I'll add that in a bit, along with a couple other weather-related bugs. --Zkyo 13:40, 28 April 2011 (UTC)

F3 toggled + shift (Crouch) + F2 (Screenshot) = Crash
This bug needs more confirmations, true or false. I personally just tested it in SSP multiple times and got no crash, just lag spikes. LTK 70 17:27, 28 April 2011 (UTC)


 * Shift + F2 used to take huge screenshots, which would lag or crash Minecraft on some computers. Maybe with F3 toggled, these screenshots are one again taken. Sign your posts btw. --Zkyo 15:45, 28 April 2011 (UTC)

Right, excuse me. I don't see any correlation between the size of my screenshot and whether F3 is toggled and/or Shift is held down. The sizes range from 500 KB to 2 MB. It might have something to do with whether or not chunks are being loaded at the time the screenshot is taken, but I'm not sure. LTK 70 17:27, 28 April 2011 (UTC)

Did another check and the toggling of F3 and holding down Shift has nothing to do with the size of the screenshot. I think this can be removed if no one else reports it. LTK 70 19:13, 28 April 2011 (UTC)
 * Tried multiple combinations of said keys, no "large" screenshots were taken. The feature appears to have been removed. - Alphap T ~ C 05:16, 29 April 2011 (UTC)

Missing drops on pickaxe
"* The last use of any tool causes a block to not drop, unless you normally get a drop from using your hands."

I have tested this and can reproduce it only on a pickaxe. Can somebody confirm this? --Sworddragon 17:43, 28 April 2011 (UTC)

You get the material on last hit in singleplayer if i'm correct, but not in multiplayer. C ali nou - talk × contribs » 19:05, 28 April 2011 (UTC)


 * You're right, this bug has been around for a while on SMP. It's not present on SSP as far as I know? I've experienced it only with pickaxes, and at its last use the block gives nothing. This includes ores. I haven't explicitly noticed it with other tools, but I have noticed that the bug is absent with shovels. I think this means that the blocks only fail to provide drops when you could normally not have mined it with your hands. In other words, as soon as your tool breaks the game thinks you've been mining the block with your hands, and in the case of stone and ore this means it doesn't drop anything. Because pickaxes are the only tools that mine blocks exclusively, it doesn't happen with shovels and axes. However, one person on GetSatisfaction reports that it does happen with swords. GetSatisfaction thread LTK 70 19:11, 28 April 2011 (UTC)

Also, you won't get snowballs on last shovel hit too. You still get the block with axes/shovels in general. For swords, there's maybe a problem about 1 block broke with it counts as 2. C ali nou - talk × contribs » 18:58, 29 April 2011 (UTC)

Buckets and Carts with Chests. NOT FIXED
I assumed that it was fixed with that update stating that buckets will no longer release their contents when opening a chest with them. When I was gathering lava (entire inventory full of buckets of lava) and then went to several chestcarts on my rails, I opened one with a bucket of lava: The lava released on top (yes, on top of) the cart and destroyed all carts with all the hundreds of rails and iron pickaxes in them.

Basically this is the summary: When opening a normal chest with a bucket it won't release the contents. When opening a chestcart with a bucket it will release the contents.

It's extremely annoying since if you make the mistake it'll ruin EVERYTHING. My client is in 1.5_2 or what's it called... The date is 28-04-2011 (DD-MM-YYYY) and my client is fully updated.
 * Wrong. You opened it too far away, so it emptied the lava instead. Cool12309(T 21:28, 28 April 2011 (UTC)

Poster is right. Interacting with a Minecart+chest both opens the chest and empties a bucket. I've confirmed it in SSP and I'll add it to the list. LTK 70 21:49, 28 April 2011 (UTC)

Crouching Falls off Edge
If you are crouching and walk to the edge of something, then stop crouching you will fall off even if you are not moving. Similarly, if you crouch to the edge of a block, then while still crouching but not moving, place a gravity-influenced block like sand or gravel right underneath you, then you will fall with the block even though you were technically supposed to be crouching on the previous block still.

Mellamokb 04:31, 29 April 2011 (UTC)
 * The most likely reason for this "bug" is that if you sneak to the edge of a block you aren't on the block anymore, as third-person mode and coordinates prove. However, this might be an intended feature and not a bug, to make it easier to achieve more precise landings on steep drops. - Alphap T ~ C 05:12, 29 April 2011 (UTC)
 * Sometimes when building (for lack of a word for it) "from beyond the edge" (try making a floating row of blocks, while standing on the last block facing to the start of the row - holding crouch; moving backwards while placing blocks) you occasionally still fall down without releasing crouch. (bit hard to explain, but it results in death often when it occurs, and is a bit annoying because otherwise its a really fast way to make a floating line of blocks) Lalophobia 09:30, 29 April 2011 (UTC)

Mob spawns when trying to sleep?
A mob spawns whenever I try to sleep in my house. Here's a video--Taneb 09:08, 29 April 2011 (UTC)
 * This feature is already known (at mojang), It happens mostly when your bed is next to a wall.
 * Try again with at least 1 space around the bed.   Lalophobia 09:20, 29 April 2011 (UTC)
 * There's another bug at work than the one where beds are against the wall. If it still happens, try breaking and replacing the bed. LTK 70 12:44, 29 April 2011 (UTC)

Fence jumping
Jumping onto a fence, presumably with an unchanged fly detection setting (I havent reproduced the bug myself to confirm yet), might disconnect you... as shown in this clip both players have this. props to Jesse Cox for stumbling into this bug ;p Lalophobia 10:12, 29 April 2011 (UTC)

Jumped off a fence multiple times, didn't got kicked. Server has flying disabled... C ali nou - talk × contribs » 15:41, 29 April 2011 (UTC)

These players are getting kicked nonetheless, so something is going wrong somewhere. I'd keep the bug listed. LTK 70 18:54, 29 April 2011 (UTC)

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.

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

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)

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.

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)

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)
