Minecraft Wiki talk:Issues

I will be in charge of this page and test questionable bugs. --Nunuru 11:22, 1 August 2010 (UTC)

Please be sure to check if the bug is SP or MP related, and if it already exists. --BopMeExtreme 19:05, 24 October 2010 (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)

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. 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? 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)

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)

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)
 * Can anyone confirm this bug please?--Idiotninja 11:03, 9 November 2010 (CST)[edit: sorry bout that]

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)

Reed
I generate a new world in SSP and i have seen 4 blocks of reed on top of each other but I had forgot to make a screen.
 * Reeds have always done that, and I think so have cacti. at 11:54, 13 November 2010 (UTC)

When minecarts will be fixed
'Notch has stated that minecart bugs in multiplayer will be fixed when beta is released. (needs source)'

http://twitter.com/#!/notch/status/29210655211 ?

It's not a clear statement, but I don't think he said it any more clear than there...

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.

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)

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)

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

cactus placet 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)

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)

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)

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.

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.
