Organization of This Page & Instructions[]

Please do not spontaneously delete an issue report or comment, unless it is patent nonsense submitted by someone who has not logged in. If possible, contact the submitter by user-talk first and tell them about your concerns. They will almost certainly oblige. As always, assume good faith.

If you're unsure of an issue, it's good practice to post about it on the talk page to see whether others can reproduce it. Make sure you're testing the bug in the correct version (for this page, that's weekly 12w05b) with no mods installed. Also, make sure to proofread your issue report before submitting it; unintelligible issue reports come off as inconsiderate and disrespectful. Finally, please determine which game mode(s) your issue appears in, and flag it with the appropriate label(s).[1] (Also, note that if, for example, a minor annoyance appears in both single-player and multiplayer, and in both creative and survival modes, you should label it as [A] , not [A] [SP] [MP] [Su] [Cr] .)

Be sure to sort issues by category, type, and priority: redstone issues go in the Redstone section, etc.; bugs go in the Bugs subsection, with major bugs listed before minor bugs, annoyances in the Annoyances subsection, with major ones before minor ones, and issues that Jeb has marked as fixed or skipped are moved to the Fixed/Skipped section. Issues that Jeb cannot reproduce, however, are to remain in their original place.

Please sign all issue reports and comments by typing ~~~ (three tildes; tilde may be found above Tab ↹ on USA keyboards, and to the right of @ on British keyboards).

There is no need to place bullet points before issue labels. Use bullet points only for comments. Be sure to leave a single totally blank line before each new issue (but not before comments), unless the issue appears directly beneath a header.

Issue Labels[]

Please mark your issue with one of these issue labels: (listed from highest priority to lowest)

  • [!!] = {{bl|!!}} = Critical bug that can crash a Minecraft client or server.
  • [!] = {{bl|!}} = Major bug. Use this tag sparingly; if there is consensus your bug is not major, it will be downgraded.
  • [A!] = {{bl|a!}} = Major annoyance. Think very carefully before flagging an annoyance as major. Is it really more important than most minor bugs? Use this tag sparingly; if there is consensus your annoyance is not major, it will be downgraded.
  • [X] = {{bl}} = Minor bug.
  • [A] = {{bl|a}} = Annoyance.
  • [?] = {{bl|?}} = Potential issue that you are unsure of or that the community (on the discussion page) believes requires further vetting. Note: do not use this label to indicate this-is-not-a-bug; instead, replace the issue's current label with [A] or [A!]. Furthermore, it is inappropriate to use this to flag something you disagree with; instead, express your opinion in a comment. When you apply this label to an issue, place it after the issue's existing labels; do not remove those labels.

Labels for indicating that an issue happens only in a particular game mode: (These labels cannot stand alone; you must use them in addition to, not instead of, the ones listed above.)

  • [SP] = {{bl|sp}} = Single-player.
  • [MP] = {{bl|mp}} = Multiplayer.
  • [Su] = {{bl|su}} = Survival mode.
  • [Cr] = {{bl|cr}} = Creative mode.

Labels for indicating that an issue is restricted to a particular OS:

  • macOS = {{OS|OSX}} = Mac OS X
  • Windows = {{OS|Win}} = Windows
  • Linux = {{OS|Linux}} = GNU/Linux

Labels that Mojang (not you!) uses: (Please place these tags in front of existing issue labels; do not remove the existing labels.)

  • [F] = Issue for which a fix will appear in the next update.
  • [N] = Not a bug; intended behavior. By definition, this label is inapplicable to annoyances; annoyances are not bugs.
  • [S] = Issue that will not be fixed in the next update.
  • [U] = Issue that Mojang has tested but was unable to reproduce.

To produce these labels, use the following code: {{bl|c}} where c is the code of the label you wish to use. (e.g., a for annoyances, etc.)

The default issue type is minor bug; you can produce this label with the shorthand {{bl}}.




[!!] After entering the Nether, the client or server will freeze up after a period of time, regardless of what dimension you are in. (Tested in single-player.)

  • Provide much details as you can, but not here. Link it to talk page. Delete my comment at same time.

[!!] Windows When you pause the game and click on "Video settings", the game crashes with "Saving chunks"

  • Try this: Close minecraft, delete the options.txt file from .minecraft folder. Restart minecraft.

[A!] Many chunk errors have generated, causing a few worlds to be trashed (Not tested on sp).

  • Provide much details as you can (seed and location is must), but not here. Link it to talk page. Delete my comment at same time.

[!!] When opening a map in a Super-Flat map, the game crashes with "Saving chunks". (Tested in sp, creative mode.)

  • Provide much details as you can, but not here. Link it to talk page. Delete my comment at same time.

[A] Windows[SP] offline. With every snapshot the fps go down. In 1.1 20 - 30, now 10 - 20. Also if you look in two certain directions, the fps slow down. In the other two directions the fps goes up.




[X] Standing middle of block that piston pushes, makes you fall through pushed block. (tested on sp)

[X] If you use piston to break redstone signal that powers another piston, signal goes away but piston does not retrac. (tested on sp)

[X] Standing on downwards pointing piston, while it retracts, makes you fall through. Also possible to walk through retracting piston. (tested on sp)

[X] This kind of 1-2 tick clock gets jammed after save/load sometimes. (tested on sp)


further instructions and statistics on [edit]

[X] When a redstone torch has once burned out, every torch placed in the same spot will burn out immediately upon receiving power and not turn on again.

[X] Some sort of bug where the top piston get powered if you have 4 pistons retract 2 pistons plus 2 blocks. Basically, the 'hidden' door using pistons does not work or is broke.=n.





[X] You can't place fence gates, pumpkins and beds without a block below them, this is often very annoying, as you have to place a block below first before and then have to remove it afterwards.

[X] if you middleclick on grass, the pointer will choose dirt instead of grass, but meanwhile it is possible to get grass with silk touch, so this should be fixed

[X] you can't get ice from silk touch

  • This is intentional, to prevent creating water in Nether. Kevin J Rattman 23:19, 6 February 2012 (UTC)
  • This wasn't the reason it was removed. It was removed do to water always forming after breaking the ice block with silk touch. Water would still be left be hind and you can get the same ice block back infinitely. Jeb is currently working on a fix for that bug so we can get ice blocks again.

[X] you will only get one halfslab when destroying a double halfslab with silk touch

[X] if you light tnt, the primed tnt won't fall in every direction with equal chances, cause radians and degrees are mixed up in the code

[X] the new fancy chests do create a lot of lag. this makes it really difficult to build a appropiate size storage room in multiplayer, cause on a medium class pc you can't place more than ~1000 chests without it making too laggy. a fix would be that only the visible chests are rendered, cause atm every chest, even chests behind you or behind a wall are rendered.

[X] Mobs can be right-clicked through glass. This is very annoying with cats and wolves; in fact just now I was trying to build a glass structure with sitting cats and I kept accidentally making the cats stand when I was trying to put down more glass.

  • I think this because of entities, not block. Since 1.8 (I don't remember exactly.), you can interact with entities (which includes mobs, minecarts, paintings, etc.) while there are blocks between player and entities. so if you break a block when there are painting 'behind' block, Paintings break first. (which obviously block should damaged first) and it goes on and on.. I still agree with that it's very annoying. Kevin J Rattman 23:19, 6 February 2012 (UTC)

[X] Branches from big normal trees and jungle trees replace everything including bedrock when they grow. easiest way to see: plant a standard sapling and build 4 1x1 towers directly adjacent around it ( you can leave the bottommost blocks to easy access the sapling. make sure the sapling gets enough light and then spam it with bonemeal till a big tree grows. with an good chance it will generate a branch that replaces the material from the tower. Same is with the branches from the big jungle trees, but one difference: there even the leaves can replace blocks, while with the standart trees only the wood blocks can replace something.

[X] Blocks can be brought into the top most layer by using liquids. Their top surface are completely dark.


[A] You can place blocks over wild grass and it will replace the grass and no seeds will be dropped.

  • I think this was intentional. GhengopelALPHA
  • This is intentional, yeh.
  • You can easily grow it back with a bit of bone meal.

[A] Middleclicking on redstone does not choose redstone dust, but the redstone block.




[X] [SP] If you put enough Items in for 2 Pickaxes or other things that can't stack, instead of whatever amount you should get, you only get 1.

  • anyone experiencing this bug, are you sure you are running 12w05b and not 12w05a? because i just tested b version and bug did not appear single- or multiplayer.
  • This was supposed to be fixed in 12w05b. 17:22, 3 February 2012 (UTC)

[F] In SSP, making a valid crafting recipe in the inventory (Not a crafting bench), then leaving the inventory without taking out the item that was crafted, causes all the recipe's resources to fall to the floor but leaves the crafted item in the inventory crafted box. This allows for item duplication. SMP not tested, but imagine this with diamond blocks. ;) - Video showing bug: http://www.youtube.com/watch?v=bjoOe8D5fMY

[!] In SSP, using Shift Click to make all of a recipe, it only makes half the items it should make.

  • anyone experiencing this bug, are you sure you are running 12w05b and not 12w05a? because i earlier tested b version and bug did not appear single- or multiplayer.


[A] Although Jeb previously stated that the Silk Touch enchant was 'fixed in an unacceptable way,' the enchant is still almost useless. There is no reason ice blocks should not be available using silk touch. Ice blocks should simply disappear when placed in the nether, exactly how water does when placed. SvenBoogie 06:29, 4 February 2012 (UTC)

  • Better yet, ice should explode when placed in the nether. It makes more sense than exploding beds.
  • This is also true of silverfish blocks there is no reason why they can't be gotten via silk touch.
  • This is in the wrong section
  • Actually this is right section. Blocks would be wrong. When something fits in two or more sections, they should be in more specific section.

[A] Although all types of giant mushroom blocks can be mined using a Silk Touch enchanted pick, once mined all giant mushroom blocks appear exactly the same, with the beige spotted texture from the top of giant brown mushrooms. Despite all blocks looking the same once being mined, and having the exact same name in the inventory screen, they will not stack together depending on what type of mushroom they are mined from originally. SvenBoogie 08:50, 4 February 2012 (UTC)




[X] In the statistics menu, when showing the Items section, spawn eggs are called 'Spawn'.

  • sounds like more of annoyance to me.
  • isn't that what the item is called, like Spawn Cow or something?





[X] [MP] If you log out under a 2m high ceiling or while standing in a ladder, you will be placed on the next airspace directly above the spot you logged out. In the nether this means you will often find yourself on top of the bedrock layer and you have to teleport down again.

[!] [U] A bug occurs when a creeper explodes, destroying a furnace. The furnace block may be dropped, but the items inside will not.

Couldn't reproduce. /jeb

[X] [MP] If you reconnect during a long fall, your falling distance resets. this is an cheat way to prevent you from dying when falling of cliffs.

[F] [MP] A very old bug but, Jeb, will you fix the mob spawners one day ?

Instead of seeing a pig inside it til the end of time. =p
( You could also add them to the creative inventory, by the way. )

[X] [MP] Sometimes in Multiplayer, Ghasts track you through thick walls and keep shooting a tunnel through netherrack. They may suddently stop or even shoot till they reach you.

[X] [Su] Shearing a Dead Bush now makes it into Pickup form, but does not damage the Shears.

[X] [Cr] Horizontal movement through fluids while flying is very slow. It should be sped up like every other form of motion is when flying.

[X] Right-clicking a Minecart Chest with a bow equiped charges the bow. When you close the chest, the bow will shoot and destroy de minecart (tested on 1.0 to 12w05a)


[A] When in F5 mode, we can't see what block we're pointing at, because of our character being at the center of the screen. It should be nice to have a view were our character would be a little at the left of the screen.

[A] When climbing Ladders if a mob enters the same block you are flung several blocks away. This is more annoying when you have a dog following you and it stands at the bottom of the ladder, disabling you from climbing the ladder.

[A] Direct Connect doesn't show the latest Server Address used.

[A] We can't select a world and enter it by pressing Enter, like with the multiplayer list.

[A] In the multiplayer list, the latest entered server is not on top of the list, like the singleplayer list.

[A] When exiting a world while in a boat, and then rentering the world, you will be ejected from the boat. Tested is SSP creative and survival.

[A] If only there could be a /tp <player> <X,Y,Z> command...

[A] Saplings in swamp biomes will not grow swamp trees.

  • Swamp trees are normal trees. Also this belongs to blocks.
  • They are not normal trees, just compare the swamp trees to the normal ones.
  • They really should have a different tree for swamps, at least it would make them less stale.
  • They are normal trees but the biome just changes their shading I think we have covered this already.

[A] macOS Pasting text into Minecraft only works with Ctrl-V and not Command-V, which is the Mac command for pasting.

[A!] On older worlds like 1.7 etc. ice starts to generate on coast lines. This happens on mp and sp.

  • This is a bug page for 12w05b, not 1.7.

-- 15:41, 3 February 2012 (UTC)

  • More than likely, biome shuffle. Terrain generation (and biome locations) were radically changed between 1.7 and 1.8, and a smaller change between 1.8 and Full Version 1.0. 1.0 and 1.1 are consistent despite adding "edge" biomes (though taiga biomes were unintentionally not-snowy in 1.0 and fixed in 1.1), but with the addition of jungles in 12w03a, more than likely 1.2 will shuffle everything again. -- 17:24, 3 February 2012 (UTC)

[A] In SMP, PVP = false, attacking another player with a fire aspect sword sets them on fire

[A] In SMP I lost two minecart chests by let them travel from station A to station B, then disconnect, connect and the minecart chests didn't stand in station A nor in station B nor on the rails between.

  • This seems to be at least a minor bug or major bug even. -Kikoman589




[X] Cats won't breed. This bug can be solved by saving the world and then loading it. Similarly, Cat can't be made to sit until next restart.

[X] Cats and kittens sometimes won't scare of creepers, they get close enough to explode.

[X] Animals wont follow you over water when wheat is in hand, once they move follow you in the water they just stop and can't be made to follow you again, until they get out of the water

[X] Cats' head, when sneaking to kill a chicken, will disassemble from their body.

[X] Cat's randomly duplicate themselves creating another cat that responds to the first cat's owner. Discovered in SMP.

[X] Cat's can't die of fall damage.

[X] When cats get in contact with water, they will teleport, but not stand up.

[X] Animals will spawn inside trees (like chickens inside leaves) http://img207.imageshack.us/img207/3776/56423736.jpg Kit Ballard 04:08, 7 February 2012 (UTC)


[A!] Animals, when you have wheat in your hand, will not follow you if they go into water that is not shallow, and get stuck there. This is a HUGE annoyance, as animals are very valuable.

[A!] When you attack a creeper, tamed dogs won't attack it with you. Discovered in SMP.

        *Not a bug, this is intended. Dogs would pretty much always die this way.

[A] Cats currently teleport to your location when you are hit by a mob (like dogs) and then do nothing except get in the way while you're trying to defend yourself. I imagine that this is a work-in-progress bug since the cat AI is still being tweaked.

  • There also seems to be a glitch where you won't be able to get them to sit down after they teleport. Probably due to the fact that they are already technically "sitting" but become standing after they teleport to protect you.

[A] I once saw my cat willingly walk into lava. It obviously ended up in cat-becue. Seen in SSP.

[A] Saw it on private server. If a nameless player enters the game Ocelots will spawn like crazy near that player. All the time.

[A] [MP] Captured animals seemingly appears outside 1 block thick 2-3 block high room, mainly the roof. If there is no roof they appear top of 2 block high wall. (pics from 12w04a)



[X] in SMP, if you in creative gamemode attack someone sitted dog, they start moving like a slime (continue sit and jumping to you) and pushing you, nothing more, it's not seriously bug, but look a bit funny.

Also they look hard to jump on even one block high



[X] Creepers and skeletons no longer strafe

  • Probably due to new AI.

[X] sometimes the creeper explode when dying. Tested on mp.

  • also happens on sp, and A LOT. if you are near the creeper, it explodes anyway.

[X] When they have nowhere to go, monsters hurt from fall damage jump up and down non-stop.

  • can be fixed by save-loading, or moving into the monster's line of sight.

[X] In SMP, in the nether, ghasts would spawn on the surface of netherrack and stay immobile, however fireball spewing still occurs. ( This happened on my server, don't know if it does on others. )

  • Tested in SP as well, and Ghasts do the same there. They spawn grounded on Netherrack, but do not move. Shooting of fireballs still occurs, however. 19:02, 5 February 2012 (UTC)

[X] If Snow Golems fall from a tall height and land in water, they won't swim up and drown. (Tested in sp.)

[!] [SP] If you let a cat sit in a offline game, save and play then online (not multiplayer) you can't let the cat stand and move. The cat don't respond. It also works vice versa, when you play online and then offline. Tested in flat world and creative.

  • This is a bug that has been around as long as wolves have, and is not restricted to any OS. The reason is that cats and dogs are bound to the player by their name, even in singleplayer, and Minecraft treats "Player" (the name of the player in offline mode) as a separate player from your identity in online mode. I agree that this is a problem. If possible, a special exception should be made for singleplayer so that single-player tames will obey anyone.

[!] After you die, aggressive mobs will still attack your dead body. Happens with all aggressive mobs; especially annoying with creepers. Tested in SSP.

[X] Creeper's new AI lets them be swept away by water. Kit Ballard 00:32, 7 February 2012 (UTC)

[X] [SP] Enderman don't teleport when attacking (least the last few I killed didn't teleport)Kit Ballard 01:34, 7 February 2012 (UTC)

      I think you were waring a pumpkin!

[X] Creepers run their "Stalk" ai script if they are behind Vines and won't advance. Kit Ballard 02:05, 7 February 2012 (UTC)

[X] Creepers run their "Stalk" ai script while in water and won't advance. Kit Ballard 03:57, 7 February 2012 (UTC)

[X] Mobs tend to "get lost" and spin in circles, shown here: http://www.youtube.com/watch?v=cl1_mEQP74k Kit Ballard 05:37, 8 February 2012 (UTC)


[A!] Can't attack mobs through Vines. Kit Ballard 00:18, 7 February 2012 (UTC)


World generator[]



[A] A super-flat world generates low enough to spawn slimes. This is extremely annoying while building. Maybe add multiple super-flat height level options?

[A] A super-flat world generates too low for people who want to work with redstone. It is hard to wire around void level.




[X] When destroying a block under a Fence Gate and then replacing the now empty area with another block, the dropped resource of the first block will sometimes appear black. Example: :File:2012-02-03 13.44.05.png

[X] wolves when entering water, turn compleately black instead of dark like they used to.

[X] Stair block does not block light correctly. Tested smooth on/off in csp, but bug should be in multiplayer/all gamemodes as well.


[X] or [A] Text overlap Items in inventory : http://img831.imageshack.us/img831/1874/35076867.jpg Kit Ballard 02:10, 7 February 2012 (UTC)






[A] Rain sound does not play in some areas, mostly the hills biome.

  • I found this to be true as well. During some of my tests, I have found that the higher you are from ground level, the rain sounds get dimmer, eventually leading to no sounds at all. It is especially noticeable when flying on creative mode. Brickman2011 02:20, 7 February 2012 (UTC)
  • This is probably for realism rain makes sound when it hits the ground so the further you are from ground level the less sound you hear. When was the last time you heard a raindrop form? Doctursea
  • Just checked from top of mountain and you can't heard the rain it's not how far you are from ground level. It's how far you are from SEA level maybe?Doctursea




[X] I am not familiar but it Afrikaans "multispeler" Is not capitalized

[X] In the original en_US language file, the "B" in "Lava bucket" and "Golden boots" is not capitalized. Related items set a precedent for this letter to be capitalized in the names of these items. This error has been fixed by the community in other English-language translations, but only Mojang is able to change the original en_US language file.

[X] In Catalan, adjectives go after the noun. This affects to potions.

  • This is also true for Vietnamese

[X] In Catalan, capital leters should be able to be accentuated.


[A] The splashes at the Title screen are not translated. (Possibly a future feature?)

  • Many splashes are not translatable because they contain jokes with phrasal verbs etc.
  • But people could make new ones for replacing them.

[A] The ending and credits are not translated.

[A] Castellano is from Spain, not from Argentina.

[A] In English (UK) in the Game menu, Achievements are named "Accomplishments", but when you go to the Accomplishments menu at the top left it still says "Achievements".
