!! When playing a custom map that involves the void (like skyblock or 4 pillar) the game will crash whenever you look at a map. Can be reproduced by downloading skyblock or others like it with an open void and looking at a map. May have something to do with the map not being able to show the actual void.

! Occasionally when traveling though a nether portal, after taking a longer than normal time to try and load the overworld, Minecraft crashes and gives an error message. This is annoying because though the world is intact all the items in your inventory are deleted. Have had this problem on both survival and hardcore but mostly only when the saves folder holds a lot of data.

!!? Sometimes, when saving & quiting from a world, the background will resize to a very small bit in the corner of the screen, causing the player to have to restart Minecraft. I beleive it happens the most when saving, then immediatly minimizing Minecraft and going to the desktop or another window.

!! Pressing F3+s crashes the game.

Tried myself, nothing. Idk system specs, but i was playing peaceful superflat on survival with tmi installed and with "Generate Structures" disabled. --24.15.167.216 17:34, 4 June 2012 (UTC)

!! When attempting to log in to a Minecraft server after migrating an account to Mojang, the client will crash. It will then show an error for about half a second before disappearing to black again. This error has occurred for the past three days. (I have tried force updating, doesn't work)

!! We have a Minecraft server that has been in use since the 1.8 Beta. Shortly after updating the map file to use Anvil, a random chunk refused to render and started spawning thousands of creepers, eventually crashing the server. We blocks away, this time with skeletons. We also deleted that chunk and restored the area to normal, but I'm not confident that it will not happen again. The player who reported issue the first time has noticed that his monster spawner trap becomes many times more efficihad been running the server on peaceful mode for a few months and recently noticed that MCEdit was updated with some compatibility with Anvil. A few days ago, we deleted the offending chunk, forcing it to regenerate, and that area returned to normal. We thought the problem was fixed, but today the same thing started happening in another chunk a few thousand ent when there is no one else logged in, and the issue recurred near another player while he was the only one logged in. Obviously, monster spawners don't spawn creepers, so it's probably not the monster spawner themselves, and I don't think it necessarily has to do with using a 1.8 Beta map since the affected area have been active locations for days before the issues surfaced. 98.113.63.61 04:22, 24 May 2012 (UTC)Omar


 * ALWAYS try to reproduce the bug in vanilla mine craft.
 * This is vanilla minecraft 98.113.63.61 00:36, 25 May 2012 (UTC)Omar

!! When playing Minecraft and using VLC to watch movies (dual screens) my computer will sometimes completely freeze. The screens go black and the sound plays in extremely slowed sound bites. The only solution is to give my machine a hard reboot. My assumption is that both programs try to grab the same hardware resources, which cause a hardware level problem. I own a 2010 MacBook Pro, i5 M520 CPU, nVidia GeForce GT 330M. This error has occurred consistently for the past week (I just started playing again.)

!! When a player is killed by a fireball fired from a dispenser, it causes the server to crash.

! Sometimes, chunks reset completely, deleting all user placed blocks, destroying houses and other structures up to the top layer.

! when I start to play the game it runs for a while before stopping, saving chunks than producing a screen saying 'Minecraft has run out of memory' (it claims it may be a bug, but might be a memory problem.
 * I've been having the same issue for a while too. Nice to see I'm not the only one, but I don't know what could be causing it. pianodude4 14:32, 8 June 2012 (CST
 * Same problem for my son. Playing on a server causes that screen very often ;( (08:00, 18 June 2012)

!! Whenever I tried to play with ATI Radeon 6630M it crashes driver. (I guess it is because javaw becomes more than 1gb)

undefined When running water comes to an open door, and the flow stops, the door closes.

undefined I have noticed that tamed wolves, while sitting on beds, appear to actually be standing up, and telling them to stand up doesn't work until the wolf is pushed off the bed.

!! When loading my world with lots of stuff, saving chunks screen appears and crash report appears for half a second.

! Every single time I log in, the client crashes. I don't even get as far as the "Mojang logo". Have forced update several times and redownloaded the client.
 * You know this is not a Minecraft related bug. Check if there is something in the '/mods' folder in '/.minecraft' folder and remove everything in it, redownload the entire client again and do not modify it.
 * No mods exist. Entire folder deleted and redownloaded. No change.

undefined When in third person frontview looking up and down 2d entity's render wrongly. They render as if you are in firstperson or backview. To get a good example, spawn some xp orbs and do the earlier mentioned. EDIT: It also happens with name labels above players in smp, but they got to stand to the left of you in order for you to see the effect well.
 * Confirmed, but for me only with XP Orbs.

undefined Shift+clicking coal into a furnace that has some coal already in it will crash the client (tested on two servers, not sure if its a problem with LWC).

!! ? When running minecraft (even without a .minecraft), once update commences, it freezes randomly while downloading a file(at 38, 50, or something else) and completely stops doing anything. Win 7 64 bit. Then, after a few minutes, it gives me: Fatal Error Occurred(4): Connection Reset Retrieving: minecraft.jar 50% @ 665.27 KB/sec
 * Googling this issue, it sounds like you should try disabling your anti-virus and firewalls and then try again.--Mattrition 10:27, 7 April 2012 (UTC)
 * try using the browser to update and then run with the regular launcher, also happens with many 32 bit EXE files on a 64 bit system
 * This has happened to me as well, if you are on windows, try downloading the linux/other version from minecraft.net (.jar version) it seems to somehow download with much less freezes.

!!If attempting to access the menu, the inventory or the chat for the first time in a Minecraft session while the Minecraft window is on a secondary display in dual display mode, Minecraft will crash, leaving a black screen and no crash report.

U !! If I left and right click a sword or any item or block, as in attack and place keys, my Minecraft crashes on both servers and clients, and on survival and creative (Haven't tested on Hardcore) !
 * Hmm, I think we need more details on this one, and also, removed unnecessary tags (! and A!), moved it a bit higher to fit into the proper sorting. This does not happen here. Bilde2910 06:02, 15 April 2012 (UTC)
 * Unable to reproduce in unmodded client. -- Orthotope
 * same, unable to reproduce, what OS do you use, windows 7 lets me do this just fine, the animation looks weird in opinion though...

! Installed MC from fresh launcher on new computer. Most sounds and no music playing in game. Check of resources directory revialed that only newsounds subdir was downloaded. No other resource files were downloaded by new launcher/updater even with a 2nd forced update. Possible that baseline launcher is not fully checking/downloading all files required for the game beyond just resource directory. (Win7-64)
 * You need to run Minecraft a couple times to make it work.
 * Able to reproduce. It happens sometimes to me too. --Anoymous712 03:42, 21 April 2012 (UTC)
 * Minecraft is loading sounds in the background, while you're playing. So you have to stay in-game for a while to download all sounds and music. --VADemon

!mp Shift+Click behavior occurring when not holding shift while within: Inventory and Chests [Survival] and Item Menu [Creative] Moving them automatically to a free spot [Survival] or giving you a stack of the item you click on / inability to move item from the hotbar. [Creative] KHRoxas 16:56, 10 April 2012 (UTC)
 * watch SethBling's vid on bugs, the shift key sometimes gets stuck, happens to me on survival, try optifine with "SMOOTH INPUT: YES"
 * Incredibly unhelpful response, you need to press the opposite: "SHIFT" key. (R-SHIFT). That will fix the complete problem for you.
 * Make sure you don't hit Alt while holding shift. If you hit Alt while holding a key in Minecraft (for example, moving forward) and hit Alt, the game will freeze and your mouse will be stuck. When you click again, the game will unfreeze, but whatever key you were holding will be stuck. Hitting the key again will fix it. Tested in Beta 1.7.3 (using You Are the Creeper, not updated) but has been happening to me since I got the game, modded or not.

!mp If an RCON connection drops unexpectedly (network issue, or rcon client is force crashed) the console is spammed with "IO: Connection reset." This generates massive amounts of log spam (40kbit/s), and continues until the server is closed or presumably the disk is filled.

! If you have a superflat world from 1.1, dying will delete ALL OF YOUR CHANGES!!! Possibly because of the Anvil conversion.
 * I think the problem is that superflat worlds don't have a set spawn point so when you die, the game picks a random spot to respawn. Your changes aren't deleted, but unless you pressed F3 at some point before you died, it's near impossible to find them again (in which case, use something like MCEdit to find them. This problem has been around since the Superflat world generator was added. NetherrackCreeper (talk) 19:57, 18 April 2012 (UTC)
 * Here's the real issue. It DOES save everything AND your spawn location. Minecraft is weird in a way. If you are spawning below 64 blocks (In superflat it's only 5) there must be a block at 64 blocks. If this is not true, Minecraft creates another spawn location and overwrites the old one. I heard about this from mcedit. And it's true, I've tested it. RyanDolan123 03:34, 1 June 2012 (UTC)

undefined Cmd + Q still doesn't make Minecraft to quit. Tested on OSX 10.7.3 - Lion

undefined mp Labeled as Fixed on the 1.2.4 bugs page, still exists for me: After executing a command in the chat box, Minecraft will not exit the entry box thus the player is stuck in talking mode. Entering another command or text will, on a few occasions, give the opportunity to exit text mode. In most cases anyway, it will write another line beginning with a slash. This deprives the player from using command such as /tpa, /home or faction related command. This did not occur before 1.2.4.
 * Unable to reproduce this. Can you give us a screenshot of your Controls option screen ? --EvilSeph 17:08, 4 April 2012 (UTC)
 * Here are my settings
 * Not fix at all --Hactarus 14:21, 5 April 2012 (UTC)
 * Got this problem too: after typing /help in talk mode (pressing T then /help), you're stuck at a "/" prompt which eventually disappears when typing "//" or "///", it's a pretty annoying bug as it blocks all controls (even pressing escape key doesn't get you out).
 * Seems to be related to video card/architecture NVidia/Sony (VPCEH for instance) exhibits it while Toshiba/ATI Radeon does not - hope this help. For the record v1.2.3 was working for both plateform.
 * This does not appear related to NVidia/Sony alone. I am getting it on a AMD Radeon HD 6950 using catalyst drivers (fglrx). Hardolaf 14:29, 14 April 2012 (UTC)
 * There's discussion on this at the Minecraft Forums. Both nVidia and AMD cards are hit, both Java 6 and JAva 7. Possibly only 64-bit machines/installs? --Freso 12:27, 20 April 2012 (UTC)
 * Lwjgl update don't work --Hactarus 13:40, 24 April 2012 (UTC)
 * Maybe it's because when you press "return" it exits the chat and then re-enters it...
 * My guess would be that it's because the new feature (introduced in 1.2.4) where the slash key also opens chat. (workaround : use the spoutcraft client) --snoepje0

undefined?

Has been a problem since 1.1). This should not be a problem and it is a pain to go into AppData every time I want a new texture pack. EDIT: EDIT: EDIT: (I know spam, but this is important): THIS IS AN NVIDIA AND MINECRAFT PROBLEM! I ran Minecraft with Intel Integrated Graphics blabla (because on other computers that's what they used and it worked) AND IT WORKED! There is some sort of conflict between Nvidia and Minecraft because IT DID OPEN THE FOLDER WHEN RUNNING INTEL HD GRAPHICS or whatever.
 * I also have a Nvidia GeForce GT 540, with 8GB of RAM, with Windows 7 64-bit, and this does not happen with me. It works fine. Just because it worked on another computer doesn't mean its a hardware problem. You also have to take into consideration that Java could have an installation issue, or maybe there is an issue with windows explorer when opening a folder, because I had a problem like that on another system, and it required me to reinstall windows.
 * Discussion on Talk Page

I think it could be the fact that in the code, Java can use variables up to a certain number, then crashes. In this case, the maximum is 3, and after that the number becomes negative. It is the fact that code CANNOT have negative numbers in it that crashes the game. There IS code made in the startup of the world to store data in it, and once it loads the tool with a negative number enchantment, the game crashes.

Minecarts/Boats
Bugs

! If a mob hits you while in a boat, sometimes it will do severe damage or kill you. This happened to me in my singleplayer world when a squid was in 1-block-deep water and I traveled over him in a boat. It was also captured on video (multiplayer) here (@ 20:04) with wolves (the wolves were following the player and they teleported when the player got too far away). I think it happens when the mobs come up from below you. Both SSP and SMP affected. --Arcooke 02:02, 5 May 2012 (UTC)
 * Confirmed in SMP with a zombie coming up under the boat. There appears to be two other issues with this bug.  The first is that it always appears to show that the player died from falling too far.  The second, which is more problematic, is that it appears that this causes the users spawn point to be reset to the world spawn point, possibly putting you far away from your current location even if you have bound to a bed near where you are (The bed in question is still intact, has not been moved, and is in a viable spawn location).

It may be that the client is predicting movement that is not actually happening (and is corrected by the server every X # of seconds). This is a major annoyance in trying to build things like docks, which may hold a boat in place until called/let loose

a mp In multiplayer, other players in a boat or minecart often appear in the running animation. This is definitely a bug, the players' feet stick out the bottom of the vehicle.

Redstone/Pistons
Bugs

undefined Newly-placed Pistons will automatically extend if there is already an active power source, such as a Lever that has previously been switched on, TWO blocks ABOVE where the Piston gets placed even if there is NO block just ONE space directly above where the Piston was placed. If the power source is deactivated or removed, the Piston will remain extended unless there was a block directly one space above where the Piston was placed.

This problem does not exist if the previously-activated power source is two blocks away in other directions (to the sides, or from underneath) when there is one empty block space between the previously-activated power source and the newly-placed Piston. It only happens if the previously-activated power source is TWO block spaces ABOVE where the Piston is placed with the empty block space directly in-between.

To Reproduce:

(1) Place a Lever on the side of a block three block spaces up so that there are NO blocks in either of the two spaces directly below the lever itself. (2) Switch the Lever ON so that it is an active power source. (3) Place a Piston two block spaces directly down from that previously-activated Lever (there should be one empty    block space directly between the Lever and the Piston). The Piston automatically extends even though it should not. (4) Switch the Lever OFF so that it is no longer an active power source. Or, just remove the lever. The Piston will stay extended.

Example (Side View):

--- --- |              |               | |               |               | |     Solid     |    Lever      |  (1) |              |               | |     Block     | (Switched ON) |  (2) |              |               | |               |               |  --- --- |               |               | |               |               | |    EMPTY      |    EMPTY      | |              |               | |    SPACE      |    SPACE      | |              |               | |               |               |  --- --- |               |               | |               |    Place      | |   EMPTY      |               |  (3) |              |    Piston     | |   SPACE      |               | |              |    Here       | |              |               |  --- ---

If the block space in-between the Lever and the Piston was not empty, the Piston would have retracted as normal in step four. Regardless, the Piston should NOT have automatically extended in the first place since there was just the one empty block space directly in-between the Piston and the Lever.

Some slight modifications need to be made to the steps above to compare the behavior when the active power source is two blocks to the side in any direction. Instead of using a lever in that situation, you can use previously-powered Redstone Wires instead. You will see that the Piston (again, TWO blocks away with an empty block space directly in-between) will not automatically extend when it is placed. However, if you have a solid block in-between (with no spaces), then it will still automatically extend as is normal.

The problem occurs when there is an EMPTY block space directly in-between the already-active power source and the newly-placed Piston when the already-active power source is TWO blocks ABOVE where the Piston gets placed. The Piston should NOT automatically extend unless there is a solid block between the Piston and the Lever.

In the MCP code, the problem appears to be a check within the "isIndirectlyPowered" method of the "BlockPistonBase" class. It is doing an additional check for power two blocks above itself without checking to see if the space in-between is empty/null.

Code:

if(par1World.isBlockIndirectlyProvidingPowerTo(par2, par3+2, par4, 1)) { 	return true; }

! Scenario: You have 2 pistons stacked on top of one another piston A on top of piston B (they can be facing any direction that does not cause one piston to be moved by or move the other upon activation). If piston B is powered after piston A OR if piston B is placed in to position after piston A is powered Piston B will duplicate piston A's power state regardless of other power input until piston A's power is removed. After piston A loses power piston B will again respond to other power sources as expected. If no power source is applied Piston B will remain powered off if piston A again becomes powered. This is my first time adding a comment to a wiki so I hope this was clear. I took a screen shot that explains things much more clearly but I'm not sure how to list it properly.

 * Discussion and more info on Talk Page

!Redstone repeaters can freeze. Appears in loop circuits, the input at 1, the output staying at 0. It seems to involve game reloading / disconnect and reconnect. A way to restart the circuit (it will eventually freeze again) is to remove the input redstone wire and place it again. Or anything that causes the input to be updated. Very important bug, also existed in 1.2.3 and maybe earlier, please fix ! (SMP, Linux 64 bits)


 * I've had the same issue on SMP,Win64 but it's not limited to a stuck repeater. I have a simple clock (one repeater and one redstone torch) powering two pistons and when moving away from the clock so the chunks unload and returning will frequently stop the clock in either the repeater or redstone torch cycle.


 * As of 1.2.5 single player survival, whenever I turn off my redstone torches(on purpose), occasionally they will not, while capable, turn back on, unless I destroy it and replace it.


 * It appears that (or as if) loading a chunk into memory doesn't cause a block update, which is needed for redstone signals to propagate. This can be a problem with said clocks and also long wires. When you move along the wire, you have to cause a block update at regular intervals or else the signal just stops. This could be fixed by updating redstone-related blocks when they are loaded into memory. --Kp 01:00, 20 June 2012 (UTC)

!While functioning (does not involve game reloading or anything), pistons can place themselves in a state simultaneously extended and not extended. This state never changes until the extended block is broken by hand, which restarts the circuit. This happens only for certain designs, but happens often. Very important bug, exists since 1.1.0 (see the 1.1.0 known bugs to reproduce, but I don't known if it is the only way to produce it), please fix ! (SMP, Linux 64 bits)
 * Reproduced. I had lots of pistons that would push lots of diamond blocks. I would hold down right click, placing blocks repeatedly. After block 3, the block train would stop. I looked at piston 2. It was retracted AND extended!

 * I'm encountering this as well. It mostly seems to occur when I'm using redstone torches to transmit a signal vertically. After the bug occurs the involved area is permanently broken.

 * Upgrading this to a major bug. Confirmed on SSP, in all cardinal directions, especially with compact vertical RS-NOR latches (the type used here).  It works a few times, but then the torches start burning out... and once dead, there is no way to fix the glitch; even rebuilding the entire structure in the same location continues to instantly burn out the torches.  This is most definitely a bug, and a serious one at that.  Seems to be easier to trigger on some worlds than others.  --Tigerstripe 10:47, 2 June 2012 (UTC)
 * Double-confirmed in SSP with ALL RS-NOR latches displayed on that page, including all vertical and horizontal designs. It's surprisingly easy to reproduce: just toggle any torch on and off frequently (about once a second) until burnout, then try to replace it: it'll either burn itself out the moment you place it, or the instant its state changes.  Doesn't matter how much you replace it, either: it's broken for good.  Definitely NOT what's supposed to happen.  This destroys all RS-NOR latches.  It may also destroy all inverters, or any circuit that relies on torches on the sides of blocks. --Tigerstripe 11:12, 2 June 2012 (UTC)

 * Aside from technical blocks, this is not a problem as certain blocks are intentionally not in the Creative inventory. This allows Creative players with access to the items the ability to build structures with them, while preventing spoilers for players who have not yet reached certain points and preventing players on servers from using these items if the ops do not want them used. --Swampert rox 19:04, 10 April 2012 (UTC)
 * If what you're saying is the intention, then why not just organise the creative menu a bit better and add the blocks when the player gets the "The End" achievement. As for the servers you mentioned, that situation might call for a new command, something like "/itemdisable 120" or that mod API they're working on.

F !cr The pick block button doesn't give you the exact block for certain block types and tends to give the drop for the target block instead. Examples, and other incorrect behavior, are listed below.:
 * On stone it gives cobblestone.
 * On grass it gives dirt.

 * On lapis lazuli ore will yield an ink sac. Corensis 02:28, 5 April 2012 (UTC)

 * More generally, it gives you the drop, rather than the block itself, unless the block normally drops nothing when broken. Picking gravel sometimes gives flint instead. Also affected: coal, redstone, and diamond ores, cobwebs, leaves, bookcases, snow (crafted block), melons, mycelium. -- Orthotope 01:29, 8 April 2012 (UTC)
 * Ah ok. I'll update the bug to reflect this. There's no point listing all those when there's a clear pattern, but the lapis rendering an ink sac is still very odd... --Mattrition 23:39, 8 April 2012 (UTC)

undefinedmp Blocks at layer 256 will not break in mp. This doesn't appear to happen in SP. Have been unable to test in survival mode.

undefinedmp When you want to break a ladder, your crosshairs will target the block BEHIND it. The way you remove the ladder is to get on the side, then hit it. undefined if a player is placing ladders and the block next to the ladder can contain a ladder, extra ladders will be placed in the second block. Frequently, the player will also be unable to directly interact with these ladders, only being able to remove them by breaking the block they are on.

Annoyances a When standing on a ladder and destroying another ladder, actually we destroy the block on which the ladder is placed.

 * Similar problem occurs when transitioning from any type of fence or fence gate block to the above (i.e. a fence placed one block level below also acts a block with halfblock height and will also cause this temporary glitch to occur)

! sp "Save and exit" will not always save changes made to the world. Some details will be saved, such as the player's inventory and the state of redstone, but not world details. Will happen only if there are lots of mobs and the system cannot handle it. Tradeworld

a When a dispenser armed with a lot of fire charges is connected to a rapid pulser, the fire charges may become stuck in mid air. They do not dissapear when the player moves away, nor when minecraft is restarted.

! Spiders spawned from a dispenser will get stuck in the dispenser block, take damage, and possibly die before being able to leave. Occurs even when the dispenser is standing alone (away from other blocks) --24.3.130.60 07:20, 1 June 2012 (UTC)

To recreate this, create a new creative mode world, build a neither portal over the old height limit (above the clouds), go through it and back. A new portal in the overworld is created. Next fly to somewhere far away, and build another neither portal (in the overworld). It will take you back to the first one generated in the neither.--Cube3 22:40, 9 April 2012 (UTC)

I created an overworld portal above 128 that lines up exactly on x/z with the nether portal (and for the sake of argument was < 128m away on the y axis. Using the > 128 overworld portal worked as expected. Using the Nether portal didn't connect me to the new >128 OR the old <128 portal. It created a brand new portal at ground level.

a! Portals doesn't link correctly between nether and the normal world. Example:

These portals were created and lit up in the overworld:

A) x: -657 y: 66 z:  837

B) x: -908 y: 219

Afterwards nether was entered from afar (not close to connect to any of the portals) and following portals was created:

C) x: -82 y: 8 z:  104

D) x: -113 y: 27 z:  104

Testing the portals gave following results:

Entering portal A resulted in ending up in portal C.

Entering portal B resulted in ending up in portal D.

Entering portal C resulted in ending up in portal A.

Entering portal D created a whole new portal.

Removing the new portal and entering portal D resulted in yet another portal

Note: the several newly created portals where all at Y: 64

a! Relating to the Above Topic i have also noticed that placing new nether portals near existing stable portals can cause the existing link to break and reform in the wrong location

a! In single player survival mode, some structures vanish after logging out/quitting, however the any items the player has remains in their inventory. This has happened several times to me, where I have built a house etc. and then logged back in to find it has disappeared. Unusually some structures have survived in some worlds of mine but others have been completely removed in others. I have no mods installed and same effect happens no matter the texture pack (including default).
 * This sounds like the chunks being regenerated from scratch, possibly due to a write error.  --King Starscream 21:29, 7 June 2012 (UTC)

a! If you have any Structure above you below y=64 the sky immediately turns black. Especially annoying and unavoidable on a superflat map. Building a house and looking out of the window - just pitch black darkness out there. Wandering under trees with fast graphics makes the sky flicker between black and normal. (Not sure if it's a bug.There's no scenario in which this would make sense. Even if I'm underground, if I see the sky, it's still blue.) Also happens in creative, so not related to the much more annoying and much less sense making void fog.
 * I have to second this.The Effect is called "Dimming".A server I play on requires a Mod which removes it together with the void fog (big buildings)
 * Void Fog and Dimming should not appear in a superflat world but it happens to me too.Can someone confirm this? 93.128.59.12
 * I can.This is definitely a bug.Maybe we should make an extra point for it.

a Logging out and logging back in while falling off a cliff will only make you take the fall damage from the height you logged back in from. It is extremely annoying with fall traps on PvP servers.

a Once entering a bed, the character will slide off and fall on the floor, but will sleep normally.
 * I think I see this too, and I think it's a bug. Try rotating the bed 90 degrees and see if you slide down it rather than fall out. I have one bed in one game where I fall out of bed (to the side) and another where I slide down the bed but otherwise sleep OK. Also try a room with a 3-high ceiling throughout. Both of my buggy beds are in rooms with mostly 3-high ceiling but only 2-high at the edges, and the beds are next to the edges of the room.

a 3D Anaglyph needs an adjustment for convergence distance, the current static effect is too strong to use without headaches on certain screen configs.

a! mp When blocks are removed by Creeper explosions, jumping into the crater will result in an infinite fall (You will appear to fall onto the block, but you will teleport up 1 layer in an infinite loop)
 * This is due to the client failing to obtain the world data after the explosion. The glitchy up and down infinite loop is because of this: The client sees a hole, you can fall in. The server knows there's blocks there. You fall in. The client keeps thinking it's just an empty hole. The server repeatedly tells the client you can't move there. That's how! Disconnecting and reconnecting usually if not always fixes this. RyanDolan123 04:31, 1 June 2012 (UTC)

! su mp Golem/tamed animal to player behavior in SMP. Major coding omissions here specifically in SMP. There's a few issues to address and some suggested solutions. --Bronzedigger 4:32, 3 May 2012 (EST)
 * Golems created and animals tamed by a specific player will not defend themselves against other players who attack them. Additionally player-created golems and tamed animals will not defend their master when another player attacks said master.
 * I suggest a simple GUI interface added to the page shown when holding the tab key which lists all players online and their pings. There could easily be a check box added for an identify friend/foe system in which golems and tamed animals of the player would adhere by. In this method a player could declare who is a friend and his golems could assume others to be hostile, thus protecting his land and himself.
 * Minions created by player 1 should be also be hostile to minions created by player 2 if player 1 has played 2 marked as an enemy via the IFF system.
 * After the above solution is implemented there is still the matter of telling to who each minion belongs to. This is not so much an issue with tamed pets as they obey commands. Golems, however, are completely identical to one another. Therefore to tell them apart I propose additional skin slots located at http://www.minecraft.net/profile which could be used to upload a player's own golem skins so player 2 who is enemies with player 1 does not approach player 1's golems thinking they are his own and get clobbered.
 * Marking this as major because current minion behavior is perfectly fine in singleplayer, but a major oversight when the multiplayer aspect is added. Needs to be changed. Anyone who has played unmodded SMP knows that invariably not all players are friendly. Player minion mobs should be tweaked to follow suit.

! Nearby (100-200 blocks) dogs/cats teleport to you, even they are seated.
 * Specifically I've noticed that previously sitting cats and dogs teleport to you as soon as you get in range.
 * Cats and dogs teleport to you at unpredictable intervals. Sometimes they don't for a while, then suddenly there they are.   Zorrothefox 15:06, 16 April 2012 (UTC)
 * I tried reproduce the bug in a new world (generated in 1.2.4). No problem with this. Maybe a bug with converted worlds (pre 1.2.3).
 * Another case: (various users)
 * Confirmed that this happens in both single and multiplayer survival.
 * Untamed wolves and ocelots follow me and teleport. This is very annoying as trying to do anything on the ground you will probably hit a wolf and make them hostile.
 * Confirmed. It seems that when I enter a wolf's line of sight others teleport to it, as normally more than 3-4 wolves don't spawn. Unpleasant.
 * This has been annoying me for a while. I'm pretty sure it started happening around 1.2.4 or 1.2.5. I keep about 25 dogs/wolves and 5 cats seated in a big room under my base in SMP. Usually while returning to the base (maybe when the unloaded chunks are loading?), they ALL suddenly warp to me. Extremely annoying if I'm in a 1-block-wide tunnel because the dogs push me around and it takes a very long time to get back to the surface. StalePhish 14:52, 17 April 2012 (UTC)
 * Not to go on and on about this, my experience is much like that of StalePhish. I too keep a lot of dogs and cats, and they were formerly in different locations (this is SMP).  Now I have to keep them all in one room (because they all end up there anyway) and having all of them suddenly warp to me at unpredictable intervals is annoying and dangerous.  It's making the game nearly un-playable.  Zorrothefox 12:38, 19 April 2012 (UTC)
 * Definitely happening. And since recently I've been exploring farther and farther distances because I've gotten in the mood to explore new areas, when I return home, all my dogs and cats spawn on me. This is a huge huge problem, because I happen to like netherrack and setting it on fire for light and there happens to be no code for dogs or cats to stay out of the fire. Even mobs will not jump on a block that is on fire, but dogs and cats will. I've been losing pets left and right.

! mp Mob movements are glitchy in SMP, leading to the following issues:
 * In a pen farm animals will appear to jump over their fences, and wander out; if the server does not shut down, they will be pulled back into their pen like a laggy teleporting player. However, they can also "jump" onto the top of the fence. While up there, they will spin around, and eventually come back down on the proper side. If the server is stopped while a farm animal is on the top of a fence post, then on server restart they ARE on top, not "tied" to the inside side of the pen, and after spinning around can walk off to the outside of the pen. I tried making fences at height 2 instead of height 1 .. Keybounce 08:24, 5 April 2012 (UTC)
 * Captured animals (also mobs) seemingly appear outside 1 block thick 2-3 block high room (like they were getting out), mainly the roof. If there is no roof they appear top of 2-3 block high wall. You can collide these glitching animals. (pics from 12w04a)  -88.194.211.57

!On a fresh, 1.2.5 map, mooshroom breeding with cows is failing for me. It is extremely frustrating to lead 3 mooshrooms on a 3 day (in-game time), (multi-save) journey back to your base only to find that the sole survivor will not get it on with any of those boring, other cows. (Maybe he didn't read the wiki....) Other possible factors: the other two mooshrooms seem to have been lost by a save game glitch. This breeding issue may be not be consistent since I have only seen a few other reports of this in the forms. Maybe it only occurs on fresh maps....

Annoyances a! Long-standing annoyance, still present: All passive mobs make noise far, far too often. Most irritating for cats and chickens, but the others are just as bad, they just make slightly less intrusive sounds. Chickens are like a Chinese water torture if you've got a lot of them. Flagging as a major annoyance this time round because it really is starting to get on my nerves. They never shut up! Not when they're sitting, not at night when they should - mostly - be asleep, and if I turn the sound down to bearable levels I lose noises I do want to hear. 82.69.54.207 02:52, 19 April 2012 (UTC)

a! Dogs/Ocelots that are sitting will stand up and try to teleport to the player after the player has taken fall damage. They will wait for the player to teleport back to the same dimension before teleporting.
 * I been doing some tests, besides isolating my chicken flocks, it would appear that the pets are most apt to teleport from sitting position, not from fall damage but from environmental damage such as lava. --Autumnrain26
 * Has anyone tried this on a completely unmodded server/client? I know it sounds anal here, but the fact that the original bug reporter was playing on a server that had a "wilderness" map linked tells me that the server was modded and I want to make sure that this behaviour is correct for the vanilla server and client too. --Mattrition 08:44, 12 April 2012 (UTC)

! mp The spawning distance for Monster Spawners is two blocks off vertically in multiplayer. Even if the client shows flames in the spawner block you have to go up two more blocks for the Monster Spawner to actually spawn mobs. -Confirmed. JOWD

! mp If mobs are confined in a small area without any chance to leave, they often break out if the chunks get unloaded and then loaded again (relog,entering portals). This can be very annoying when collecting Mobs for XP farms or iron farms.

! mp Mobs do not spawn at a certain height is smp. Even with all chunks loaded mobs will not spawn. I'm unable to find the exact spawning height, however I do know that mobs will not spawn at 230+
 * Actually, it's 240. Or more accurately, mobs won't spawn within the highest 16 meter section that has at least one block in it. This is because the game tries to not spawn mobs above the highest section, but it uses the bottom of that section as the limit instead of the top. I'm not sure why that check is needed at all since mobs won't spawn in the air anyway. Last username 11:18, 11 April 2012 (UTC)

undefined Mobs in chunks at the edge of the loaded area (i.e. in a chunk adjacent to chunk that is not loaded) are not updated. If the render distance is set to Normal or shorter, mobs can spawn in these chunks but never have the chance to despawn, leading to an accumulation of mobs in limbo. Since these mobs still count toward the total number of mobs, this results in a gradual drop-off in the number of "active" mobs unless the player continually moves around to change the loaded area. This is demonstrated in this video by Last_username. Phssthpok 17:08, 9 April 2012 (UTC)

undefined Iron Golems will appear to glitch through blocks if trapped in a hollow 6x6x6 cube filled with water, no matter how fast your computer is (probably, I tested this on a 16GB RAM computer).

undefined Mobs no longer spawn on bedrock, which alters bedrock's functionality in a way unintended by SMP server admins and makers of custom maps who build bedrock structures. This seems to be a violation of the previously established principle that hostile mobs could spawn on any fully solid block. FifthWhammy 15:28, 24 April 2012 (UTC)

undefined Mobs sometimes "spin". I'm speculating here that this is the result of the AI Pathfinding attempting to move the mob and not finding a suitable path. Easily reproducible by pushing/dropping/having mobs (namely villagers) move on top of fences, but there may be more complex cases such as when a path node is no longer navigable due to a dynamic terrain change, or unexpected terrain behavior such as falling through cobwebs (which does a complete spin, as opposed to a short circle). As another example, I have also witnessed pigs run in circles trying to get away. Whether it was attempting to get into a 1x1x1 hole and failing because it hit perfect orbit or could not run away in the jungle, I'll never know.--PlNG 00:17, 29 May 2012 (UTC)

Annoyances a In the Nether, mobs are not carried away by lava. That makes it impossible to build autonomous pigmen-collecting towers as can be done in the overworld with water. The only alternative is to use an impossible amount of redstone and pistons to push the mobs where wanted. But anyway, any flow of lava should carry mobs. Reported since 1.2.3.
 * I'm currently using 1.1 version (Due to some map editor cannot support Anvil yet.) and I found that lava flow does not affect even in 1.1. not just 1.2.3 and 1.2.5. Just want you to know. Kevin J Rattman 14:23, 11 April 2012 (UTC)

a Please fix "shadow mobs": Mobs that spawn inside the player's protective radius and then are immediately removed. This frequently occurs while quickly removing material such as dirt or quickly removing dynamic material like gravel and sand. Occurs on all difficulties, all light levels (even surface, sun, midday), even on Hardcore. Called shadow mobs because they do not have any lighting applied to them and are removed before the game lights them. Happens often enough to cause a nasty flinch.--PlNG 05:12, 12 May 2012 (UTC)

a There shouldn't be a limit to how fast experience orbs can be picked up. For example, if you kill 100+ mobs at once (ex: using a splash healing potion on a zombie dungeon spawn trap), you have to deal with almost 2 minutes of yellow/green flashing light as you absorb the XP one orb at a time.

a Performance issues affecting peaceful and hostile mobs. Basically, having large numbers of mobs slows machines down, and clients in multiplayer. The worst affect seems to be when mobs are right at the edge of "client range". However, a test with 21b where the "server side" died, and the "client side" kept going, showed that that same machine had great performance with no mob updates.

In other words: The behavior seems to be "Send all mob information to the client every tick; have the client update a lot of information all the time", regardless of whether or not it is needed.

Idea: First, a peaceful mob not in line of sight is of very low priority to the client. A hostile mob in line of sight is of high priority. In general, the server won't know where the client is looking, and cannot tell line of sight of the player easily, but can tell line of sight of the hostile mob, and if the hostile mob has aggro on the player. Based on this, you can have the server update mobs based on things like:
 * A) In the same 16x16x16 mini chunk
 * B) In an adjacent one "close by"
 * C) Has line of sight for long range
 * D) Has line of sight for mob's range
 * E) Has Aggro
 * F) Is hostile / neutral / peaceful (neutral == things that are peaceful now but might become hostile: pigmen, wolves.)

Note that an entity at very different heights, with no LOS is not of interest, but it might fall to your level and in front of you; changing the condition of a mob may result in it being forced to be updated, in much the same way that Optifine forces the chunk you are in to be updated "now" while other chunks are updated smoothly.

 * The !! label will stay,however this should get a !,but then again,this "crashes" Minecraft.

! mp After converting my server world's block height limit (in Minecraft 1.2.3), all chunks had at least one type of block missing. The first one I found was a chunk with stone missing, and that also made floating sand, gravel and minecarts which I originally placed for transport. My server's town was about 2000 blocks by 2000 blocks large, and was entirely devastated by this bug. I started making a new town in a new world now. The old town map is still available in my server, so if you need pictures, just ask me.

! mp Spawn Location is reset to 0,50,0 after the first /stop command.
 * Create a new world with the server, invite players. If a player die, he will appear in the real spawn. (but looking in the level.dat with NBTEdit will show 0,50,0...)
 * Then, /stop, re-start the server, re-invite players. If a player die, he will appear somewhere around 0,50,0. So he will have to find where was the original spawn location, which is really annoying.
 * This has been fixed in CraftBukkit, so, to the Bukkit team : could you fix that, please ? =)

! sp If for some reason, the game deems the location of the End Portal in a stronghold to be unsuitable due to excessive generation / conflicts, it ?moves the location of the end portal?, however it does not update the Eye of Ender's coordinates. In some cases, this may mean that the End Portal room is COMPLETELY disconnected from the rest of the stronghold, or not even there. Reproducible on seed: tjercauiW Hash:(-650269854) Eye leads to 603 17 1044 Actual portal coordinates: 597 14 1007. --PlNG 12:11, 5 May 2012 (UTC)
 * Reproduced,also cut off by cave wall.
 * My portal was cut away by new terrain generation. Tried to delete chunks using MCEdit, now the ender eyes lead me to a point where's no stronghold and no portal.

undefined When converting a world from 1.1 to 1.2.5 (to Anvil), some chunks appear to be old, some buildings are missing. Maybe related with mods (in 1.1 OptiFine and TMI, in 1.2.5 only OptiFine A9), but i don't think so. --Galaxy_2Alex (Talk)

 * Okay, sorry. I tried it now with Vanilla 1.2.5, and again, the building was old. Pictures: Before converting and After converting. Is it a problem when there are mods in the 1.1 jar? Is maybe the world too big? It has 137 MB... --Galaxy_2Alex (Talk)

a When upgrading a map, changes to the world generator will create strange occurrences in the world, such as walls of large cliffs next to oceans.

Graphical/Lighting
Bugs

! mp Glowstone sometimes doesn't light up chunks in SMP, allowing mobs to spawn in the area. Example: http://img215.imageshack.us/img215/1117/glowstonebug.png Walking into the dark area generally causes the light to update (but not always), but logging out and back in reverts it. The same chunks seem to be effected. Putting torches in the area works as a band-aid however. DarkWolff 01:46, 5 April 2012 (UTC)
 * That looks chunk aligned. Was that section made (lighting; placement of glowstones) prior to anvil, or after anvil? Keybounce 08:27, 5 April 2012 (UTC)
 * Yes, it is chunk aligned and yes the map was converted, though I extended the glowstone just pass the dark area in 1.2.1. I don't recall if I tried replacing blocks, but will try when I get home. I've mostly been putting down torches and removing them whenever there is a patch (been around since 1.2.1) to check if it was fixed. I've also seen similar bugs in other areas with lava, but never as bad as this. DarkWolff 15:23, 5 April 2012 (UTC)
 * Ok I tried replacing he glowstone and when I relog the area becomes dark again. Basically the glowstone will not light up the area in those chunks. DarkWolff 00:40, 6 April 2012 (UTC)
 * Foo. If it maintains after you replace the glowstone and force the lightmap to be updated, then it's not the issue I was thinking of. Keybounce 01:14, 6 April 2012 (UTC)
 * This is bug is also for Lamps as can seen here http://img836.imageshack.us/img836/7803/lampr.jpg This is after I've replaced Glowstone with Lamps because of having this issue.

! New lighting system severely drains FPS since 1.2. This problem persists in 1.2.5. Lighting changes in-game caused by lava, redstone lamps, redstone repeaters, and/or pistons cause heavy FPS drops and/or stuttering on low- to mid-range computers. This problem didn't exist in any version prior to 1.2. It looks as though there is now a lot of excess load on clients to calculate lighting changes, whereas pre 1.2 Minecraft forced the server to deal with lighting calculations. This essentially makes the nether and busy piston/redstone contraptions unplayable as the FPS lag is extreme. d3fin3d
 * Should this be updated to a minor bug? d3fin3d
 * If the result is that the game is unplayable on computers that meet the game's minimum requirements, then yes, I'd call it a bug. Keybounce 08:30, 5 April 2012 (UTC)


 * Unfortunately, even with 4GB of RAM allocated to java, and thus minecraft, this lighting memory decay issue causes me to place blocks twice. It is not a mouse problem, but an FPS issue. Even though I can play more graphically intensive games. This issue is occurring in offline mode. SoaringMoon 11:17, 13 April 2012 (UTC)


 * Same here. Also offline mode. I have tested it with different mice. If redstone is near by, it always generates long right clicks, so that i place blocks twice, can't open/close doors and can't use switches. This is a very annoying bug (64 Bit JVM, 2GB JVM memory, Core i5 2.52 GHz with Intel HD Graphics). 217.255.24.162 18:36, 22 May 2012 (UTC)

! As of 1.2, there are consistent unrendered chunks as there were prior to 1.8 or 1.9 beta. These unrendered chunks show up in random spaces and can appear in a chunk when returning to an area when they hadn't been there the previous time through, even though the user has not logged off of the game. When a user tries to walk over these areas, they will get stuck or fall out of the world. The user can safely ride a minecart or a boat through the chunk from one side to the other, although both the minecart and the boat will appear to turn slightly off of the direction they are going and tilt to the side a little. This is a client side issue as one person will see the unrendered chunk but another person will not when on MP. Logging out of the game in play and back in (but not closing the client) will usually fix the local render issue but not eliminate them all together. This happens on vanilla servers and clients as well as clients with texture packs in place. Examples: http://dl.dropbox.com/u/2274101/2012-04-07_10.29.14.png, http://dl.dropbox.com/u/2274101/2012-04-07_10.29.21.png, and http://dl.dropbox.com/u/2274101/2012-04-07_10.29.40.png. Pewmayman 14:58, 7 April 2012 (UTC)

! New lighting system allows phantom sky-lighting in large covered areas. Bug is easily reproducible. There is a community fix titled "LightOff" which addresses the issue.

! Sometimes when you remove/place a block the graphics will not update. This causes blocks you place to be invisible, blocks you remove to look like they are still there and doors/trapdoors you open to look like they are closed. This only happens in certain chunks. Restarting Minecraft fixes the problem, but it soon reappears in other chunks. If you place a torch where the bug is active the light will still spread in the parts that work normally and vice versa. I am only able to reproduce this bug on one particular computer (out of two I tested on) with Windows XP (the other has Mac OS 10.7) but I have seen it happen in a let's play on YouTube.

! This video quite clearly shows the problem, a graphical, pixel-thick transparent grid around blocks, grass blocks being most prevalent, and the torches have been affected as well. A high resolution texture pack makes this unbearable, but with a completely vanilla windows client and the default texture pack it is still painfully obvious that shouldn't be there. I noticed it after I installed java (64 bit) 7 update 5 after having minor problems with my client, but I tried java 6 update 33 (using in video), same results, I suspect the new versions may be the cause. --Greatwroth 09:58, 13 June 2012 (UTC)
 * [edit] I've used an uninstaller program to completely uninstall both 32 and 64 bit java and clean up relevant registry items before reinstalling it (java 6 update 32 as well as the earlier mentioned versions) as well as starting with a fresh minecraft client off the site but I still get the same game killing eyesore. I don't understand, the client hasn't updated recently (not to my knowledge at least) neither has my graphics drivers (which are working just fine in EVERYTHING else), I just can't seem to pinpoint the problem. --Greatwroth 23:12, 13 June 2012 (UTC)

Bugs !!Not sure if this qualifies as a bug, but I believe it does. OpenAL32.dll and OpenAL64.dll both had problems. If I tried to enable sound, the game would crash, and with certain mods (such as IndustrialCraft) the game would crash. None of these times it gave an error report. Currently the workaround I've found seems to be deleting the .dll files in %appdata%, forcing Minecraft to use the Windows default ones.

F !! In Español (MX), going into the opciones menu and clicking controles will crash the game. NetherrackCreeper (talk) 19:44, 4 May 2012 (UTC)

To make the crashing stop, go to the %appdata% and .minecraft and go to the bottom of it and delete options. Your welcome, fine sir.

! Cyrillic UTF-8 letters in chat and signs and their GUI are typed in basic Latin UTF-8
 * Just replace old lwjgl (2.4.2 distributed with Minecraft). Newest available 2.8.2 has no this bug. --Alcr 06:03, 7 June 2012 (UTC)

Annoyances

a! In the Arabic language, letters do not connect correctly (e.g. 'ا ل ل غ ة ا ل ع ر ب ي ة' (without spaces), when it should be 'اللغة العربية') --Tredontho

a In Romanian, 'Fire Charge' sticks with the English name. It should be called 'Bilă de Foc' --MCKMan

a In Czech, Wooden hoe should be called "Dřevěná motyka" not "Dřevěnná motyka"

a In Finnish, base potions use the word "Taikajuoma" (Potion) twice.

a In French (CA), The yellow flower should be called "Pissenlit" and the red one, "Rose". End Stone should be "Pierre du Néant" and Pressure Plate, "Détecteur de Poids". Mushroom Stew should be "Ragoût de Champignons" and Minecart, "Chariot de Mine". Boat should be called "Bateau" and The Chicken Spawn Egg should be "Oeuf de/d' Poulet".

a Quenya (elf language I believe) language pack has some problems. Several of the names have a space or two at the end (ex. lapis block is "Luine Quile Colca  ") for no reason. Also, some things have an English name (ex. cualdron). -Partonetrain (No, I don't have an account on minecraft wiki, so I just put my IGN)

a! In Polish language polish diacritics render properly in menu and tooltips, but they get typed on signs as if Alt button wouldn't be pressed("ś" as "s", etc), except for "ć" which when typed renders as "æ".

Also, "Lapis Lazuli" should just be "Lapis Lazuli", "Lazuryt" means "Lazurite", the actual mineral in it. And while indeed correct, translation should reflect on the name from the English version. 83.28.198.241 18:44, 19 June 2012 (UTC)

Bugs

!! LoadLibrary with error 998: Invalid access to memory location. This happens when trying to log on making the game unplayble *this is a completely unmoded game I just bought and have and error after error this being the most recent but unable to find a soultion to it, I have not been able to play at all*

Annoyances

a! When playing offline, we will be named "Player", which is really annoying when playing on a LAN server without internet. It will also affect the achievements and statistics. Please fix the launcher to use the name we want when being offline.

a! Loader buttons are transparent, seeing dirt.png image through them.

a! Wiki doesn't send mail to *@inbox.ru Check blacklists
