Bugs

!In some computers (1.75 GB of RAM, 32-bit, 2.71 GHz, Windows XP SP3, Java 1.6) the world will still not save blocks, but will save player configuration. Example seen here http://imgur.com/a/xixYo#0 (1st and 2nd screenshot taken in a run, the 3rd one is after reloading the world). Here's a debug profile made while placing the blocks, if it helps. undefined --Manuelschi 17:06, 5 July 2012 (UTC)

![MP] Players falling through world and getting socket exception when connecting or going through nether gates. Reverted to 26 and I was fine. Moved back to the spawn (my base is some ways away) and updated to 27 and everything is fine. Went back to my base and re-logged and it happens again. We were able to teleport me to the spawn and I was fine. Had someone else come to my base and re-log and he gets the same exception. I have also experienced this when travelling from the nether to a portal at this base.

I have completely re-installed minecraft and java. I started a single player creative on the same seed and went to the coordinates and was able to exit and re-enter.

seed: ubik rough coordinates: x = 1473, z = -155 undefined --Neema 00:37, 7 July 2012 (UTC)


 * I can confirm this bug. I'm also getting "Internal Server Error" while in the nether, and getting booted. --SullyTheUnusual 15:58, 7 July 2012 (UTC)


 * While I personally have not experienced these "Socket Exceptions" of which you speak, I have experienced falling through unloaded chunks into the Void after using a portal before the game loads the chunks and puts me back in the portal. TorchicBlaziken 23:59, 7 July 2012 (UTC)

undefined CMD-V does not work to paste things into Minecraft. Dinnerbone said he was having trouble with this because he didn't have a Mac. However, Minecraft recognizes the CMD keys as LWIN and RWIN in the controls menu, so enabling the LWIN-V and RWIN-V combinations to paste might do it. CTRL-V does work on a Mac, but it is unintuitive for Mac users. TorchicBlaziken 21:14, 28 June 2012 (UTC)

Annoyances a My SMP server uses 60% CPU when no users are logged in. The 1.2.5 server used 40%. AFAIK, there is no good reason why it should use any amount of CPU when nobody is logged in. My server uses much more electricity than neccesary because of this. Thue 15:50, 5 July 2012 (UTC)
 * I'm running two servers on mac at the same time, getting a 2% CPU usage when noone logged in, it gets up to 50% when I log in from my computer (so, 2 Minecraft Servers + Minecraft Client). I usually got al least 75% usage on previous versions (same 2% when no one logged in). iMac 21.5 late 2010, 8 GB RAM (1 GB assigned to every server, and 2GB assigned to Minecraft client). --Asmcsl 17:03, 5 July 2012 (UTC)
 * I have a relatively old Athlon64 X2 3800+, but still shouldn't be using 40% or 60%. Perhaps you have killed your enderdragon and destroyed your end healers, which seems to be what is using lots of CPU in 1.2.5 (From profiling the partially decompiled 1.2.5 source code from bukkit. A 24x24 are is always loaded in each of the three worlds). Thue 00:29, 8 July 2012 (UTC)
 * Now, after running a good deal of time, it actually seems to have settled down to run at ~6% CPU, which is obviously much better than in 1.2.5. Don't know why. It woul still be nice if it didn't use any CPU when nobody was connected, of course, like fx my apache and sshd servers. Thue 00:34, 8 July 2012 (UTC)

a! All of my sign text has disapeared, and mob spawners only spawn pigs.
 * Already fixed: https://twitter.com/Dinnerbone/status/220892547847954433

a! Every time I try to update Minecraft through the launcher it stops at about 5-9% percent downloaded (I've checked the minecraft.jar, only metainf folder was there). --66.219.226.219 22:03, 7 July 2012 (UTC)

undefined

--SoaringChris137 21:31, 5 July 2012 (UTC)
 * Spawner egg or mob spawner? Either way, the game is not supposed to give you the chance to do that. It's like trying to use a spawner egg to spawn an item entity, it will crash. Since it cannot be reproduced on vanilla minecraft without 3rd party programs i vote for deletion.--Manuelschi 22:53, 5 July 2012 (UTC)
 * It was a spawner block, like you find in dungeons, and because in the previous snapshot the special spawner permissions were added but only accessible through 3rd party editing I don't think this can be overlooked. --SoaringChris137 23:26, 5 July 2012 (UTC)
 * This has been fixed, but I really wouldn't call this a critical bug. It's custom behaviour that we've never supported before or had intentions of directly supporting. Dinnerbone 08:16, 6 July 2012 (UTC)

fmp Every user that logs into my SMP server gets kicked off immediately, with the following message in the console (no crash report recorded on server nor client): --Inertia undefined
 * This may be caused by 'view-distance' in the server.properties file being set above the default value of 10. --Recondite 20:32, 5 July 2012 (UTC)
 * Good call. Indeed, it was the view-distance.  I had it set to 15, but taking it back to the default (10) seems to have fixed it.  But in the previous build, having it set to 15 seemed fine. --Inertia

Gameplay
Bugs

! NPC Villages will lag my computer down to <1 FPS. I don't know what's causing the problem but this has never happened before and I have to delete my [Player].dat file to respawn and the lag stops. I cannot produce a debug profiling due to major lag. Will list specs if needed. Zmr333 01:58, 7 July 2012 (UTC)
 * Not a crash bug. Downgrading and moving. --Mattrition 15:25, 7 July 2012 (UTC)

!mp Player 1 can push Player 2 around on their screen but Player 2 doesn't move on their screen. Therefore Player 1 can push Player 2 in lava and Player 2 will take unnecessary damage.-- QuAd205 03:00, 6 July 2012 (UTC)
 * I've had this happening too. Seems to glitch with any entity pushing the player. I was shot by a few skeleton arrows and walked around to hit them but saw them firing at a wall while I got hurt. Done using the minecraftserver.exe Lukesoccer21 05:42, 6 July 2012 (UTC)
 * Happens for me too, though I've noticed it seems a bit inconsistent. I've been able to push a friend and when they move, they notice they're suddenly elsewhere as described above, other times I've pushed them, then when they moved they've gone back to where they originally were as if they hadn't been pushed at all. -TheWyo 20:01, 6 July 2012 (UTC)

!? Any blocks above Y=191 when logging into a single player world become invisible. Logging out on a structure above this level on SSP made me unable to move, place blocks, or break blocks because I was glitched into invisible blocks. --68.33.111.198 16:08, 5 July 2012 (UTC)
 * Seems to also occur in multiplayer for me. Anyone else able to add any more information? -TheWyo 23:14, 5 July 2012 (UTC)
 * Occurs for me as well. Can produce screenshots if need be. Also, the blocks seem to reappear upon a block update; the structure that disappeared for me was a farm so when farmed soil became wet farmed soil, it showed up. When melons grew, they showed up. Placing a block on the newly appeared blocks causes it to turn into whatever block is actually there (making the old block visible). Exiting the game and returning makes all blocks invisible again. -Bleaker 01:14, 6 July 2012 (UTC)
 * This happened to me in the Nether. I thought I screwed something up in MCEdit. I couldn't interact with the blocks, but they stopped my motion. I was flying upward into a ceiling of bedrock in creative. I could not break them or place blocks, though I didn't do much testing as I thought it was my world file. --5thHorseman 04:05, 6 July 2012 (UTC)
 * It is acting somewhat like an ordinary chunk error except that it happens above y:190. --Inertiahttp://youtu.be/_35mQCUjCMc

! When water current pushes you into a corner, you start taking damage. Screenshot: http://i.imgur.com/uzMEc.png (Note: this screenshot was taken in Peaceful mode.) --Techokami 19:32, 6 July 2012 (UTC)
 * seems related to the "Player 1 can push Player 2" Bug stated above. Something's wrong with the client and server not matching up. Was this done on a server or "singleplayer"? --Lukesoccer21 17:17, 7 July 2012 (UTC)
 * It was done in "singleplayer". As long as there are blocks at the head level forming a corner, and a diagonal current pushing the player into said corner, the player takes damage. The game probably thinks the player is inside the blocks and is suffocating. --Techokami 22:16, 7 July 2012 (UTC)

undefinedcr Crafting something in Creative Mode (I know, why should I...) in the 2x2 crafting field generates the crafted item and drops the old items like they were not used after closing the menu. I made four sticks with two pieces of wooden blanks in this Screenshot. Doesn't occur in Survival Mode. --Freakedenough 18:49, 5 July 2012 (UTC)

undefinedsp Pick Block is not working. Ristovski 14:16, 5 July 2012 (UTC)
 * Is working for me, what block are you trying to pick and do you have it in your inventory? -- Mustek 14:28, 5 July 2012 (UTC)
 * Cleared inventory, can't use Pick Block on ANY block. Ristovski 14:33, 5 July 2012 (UTC)
 * Restarted Minecraft, pick block works fine now, I guess some LWJGL error. Ristovski 14:37, 5 July 2012 (UTC)

undefined When crouching next to a block that has vines, the player will "glide" as if on ice.
 * Default property of ladders. If you sneak on a ladder you glide just as you said. Vines have the properties of ladders, but you need to push against a wall to ascend. --Manuelschi 17:17, 5 July 2012 (UTC)

undefined With some bed placements, you fall out of the bed instead of sleeping in the bed. See File:Falloutofbed.png to reproduce this. Seems like some part of the game code still thinks the player is standing, so it's trying to prevent him from suffocating by pushing him away in some direction. -- JonHa97 18:44, 5 July 2012 (UTC)

undefinedspI destroyed many ice-blocks in a frozen lake with an enchanted axe (fortune III, efficence IV, unbreaking III) until the axe broke. The last ice-block disappeared and there was a hole. Around it there was water. I couldn't swim through it. I placed blocks from the bottom of the lake to the top and the ice-block I destroyed came back.

undefined Eggs thrown by dispensers will sometimes spawn chickens in a block. The chicken will suffocate and die. Other eggs function normally. ~Cm283 20:21, 5 July 2012 (UTC)

undefined Dropped items sometimes refuse to be picked up. I had a sapling that was dropped from a tree, and I couldn't pick it up. I tried to remove blocks under it, but that didn't work. After about a minute of walking through it, it popped into my inventory. http://i.imgur.com/jMcwx Happens rarely, but it has happened several times now, in different snapshots. --Blunderbrain 10:48, 6 July 2012 (UTC)
 * The sapling is resting on a leaf on the server's screen but it's not on your screen. It should teleport back up and fall again for you, is that correct? LB 23:42, 6 July 2012 (UTC)

undefined When I Use Minecraft Fly Mode,The Game Exits,Windows 7 279GB Ram (Bootsector Files Full) Booted From 279GB D: Drive
 * Wrong section, wrong tag and learn to use your capital letters. Before I upgrade this to the bug section, what exactly happens? Do you mean when you try to use creative fly mode?
 * The fixed/skipped section is for Mojang only. We appreciate you trying to report bugs, but please read through the top of this page so you'll know how to use this page correctly. Incorrectly reporting bugs is just as bad as not reporting them at all. Additionally, by "fly mode", do you mean the game mode, Creative? Is there any sort of crash report or anything? --Keithicus420 18:30, 6 July 2012 (UTC)
 * Pretty sure you meant 279 GB HDD space. Nobody has 279 GB of RAM unless you're running a mainframe.  --99.28.9.131 04:41, 7 July 2012 (UTC)

undefined When right clicking a minecart with furnace the minecart moves foward on the track. You cannot access the furnace to place wood or coal --Kain837
 * This is how it has always been? You hold the fuel in your hand and right-click to add one of said fuel item into the powered minecart. This will cause it to run until the fuel is depleted. You can't drop in an entire stack at once. --Techokami 01:42, 7 July 2012 (UTC)
 * oops, your are right about dropping a whole stack in, but if you hand is empty and you right click the cart will move 1 block forward on its on, no coal was placed in the furance --Kain837

undefined Potion effects are lost when you travel to the Nether from the normal world. --24.130.201.24 05:23, 7 July 2012 (UTC)
 * Can you confirm that its the effects that are lost or just the particles? I am almost certain it is just the graphical effects on the player because doing this also removes flame particles from the player but they will still take damage --Mattrition 14:13, 7 July 2012 (UTC)

mp! There is no way to get on a multi-player server other than ones that are 12w27a.
 * ...and you should not be able to. Because it just would cause lot of more bugs, if not crashing. --93.106.71.228 20:04, 7 July 2012 (UTC)

undefined Chests do not update properly. Placing items in them, or taking items out of them may fail. Ex. you shift-click a stack of dirt into a chest, it appears in the chest. If you leave the chest and click the inventory slot the dirt was in, it re-appears in your inventory - it seems, it has never been placed in the chest. Also, the chest closing or opening sound and/or animation may not play. --77.189.31.93 23:23, 7 July 2012 (UTC)

undefined I don't need full set of libraries to get 30 lvl on table. Something like 10-15 is sufficient. It shouldn't be. There should be a reason to build full set of libraries. --velvetpro 23:40, 7 July 2012 (UTC)

Annoyances

a When you die, and respawn (no beds involved), you are teleported to the highest point of the spawn region. This makes it hard for custom map makers to create indoor maps without players getting out of the map when they die. I don't know how long this has been happening, but I noticed it in 12w26a. --76.188.50.201 16:51, 5 July 2012 (UTC)

a! When extending 4 pistons around a lava source block in the middle, all the pistons extend, but one or more also appear to be retracted at the same time. When this happens, the affected piston(s) are frozen in the extended position. Smashing the extended portion seems to reset them. --SullyTheUnusual 14:50, 6 July 2012 (UTC)

a Portals built above Y=128 in the normal realm do not link up with portals in the nether properly. (Bug that has been around since anvil was implemented in 1.2) Water99 19:49, 6 July 2012 (UTC)


 * One solution that I can think of (without expanding the Nether to use the newly available space) would be to add 2x vertical scaling to the Nether similar to the 8x horizontal scaling already implemented in the game. TorchicBlaziken 23:59, 7 July 2012 (UTC)

a Birch and Spruce trees will not grow directly beside one another with or without bone meal; however, Oak and Jungle trees will grow. Dotsarecool 08:25, 7 July 2012 (UTC)

a! mp (possibly single player also) When being pushed against a wall by a water current or trying to push through the force I fine I loose health as if drowning. Also when walking around the world, I was going across a sand desert and the same thing happened again (there were NO cacti around me). I lost health. I have marked this as major as I have already died twice from being stuck in a hole and unable to get out because of the water current causing the health to drop (StormKitten_1) --2.26.50.37 08:39, 7 July 2012 (UTC)

Bugs ! Funny bug :) When an arrow (e.g. from skeleton or player) is on rails, it will stop minecart. --velvetpro 21:57, 7 July 2012 (UTC)
 * That's a bug? It's been around forever and I always assumed it was intentional. --5thHorseman 00:45, 8 July 2012 (UTC)

! Look straight down, jump and try to place a block. Sometimes it works, sometimes the block appears and then disappears. The previous snapshot did not have this issue. --Croftyraider 17:05, 6 July 2012 (UTC)
 * I've seen this a lot with peaceful mobs (It would probably happen with hostiles too but they're - you know - hostile) nearby. It's like the client thinks it's OK to place the block (and it looks so to me as well) but the server is a tiny bit ahead of me so it sees that the mob has walked within the bounding box. I imagine it's similar when you're jumping. By the time the server sees that you want to place the block, you're already coming down. --5thHorseman 20:50, 6 July 2012 (UTC)
 * I have the same. When you manually click each block in good time, it is better. But this is a bug ofcourse. --velvetpro 21:40, 7 July 2012 (UTC)

undefined Normal-sized mushrooms can't be planted outside at night. This is because the skylight level is always 15, even at night, and the reason for this is so crops and flowers don't uproot themselves every night. Perhaps there could be a workaround for this. It is intentional that they're not supposed to be planted outside in the daytime, but they don't even work at night. TorchicBlaziken 20:39, 5 July 2012 (UTC)
 * It is my understanding that normal-sized mushrooms cannot be placed directly underneath the sky, regardless of the light level. Also, this same phenomenon (possibly a bug) existed in 12w26a. --68.251.42.233 21:56, 7 July 2012 (UTC)
 * This is not a major bug; downgrading to minor. --68.251.42.233 22:00, 7 July 2012 (UTC)

undefinedsp Priming a Tnt, exiting the world and then logging back into the same world will cause the tnt to fall through the block under it. Video -- AndyPala 15:52, 5 July 2012 (UTC)

undefined Free-floating sugarcane blocks found. These don't appear to have anything below them, so presumably maybe not the same issue as the invisible cactus bug. Logging out and in again while standing in front of the item cleared the issue, and then the lower canes were also hittable. --Simons Mith 19:24, 7 July 2012 (UTC)
 * Did you walk a long distance to find this? I'm pretty sure this has to do with unpopulated chunks being populated without letting the client know, and then the sugarcane must have grown. LB 01:17, 8 July 2012 (UTC)

undefined Fires set by lightning neither burning nor burning out correctly. I found a burning block of sand found in the desert. It didn't go out although I observed it for some time, and standing in the flames didn't set me on fire. As above, I expect logging out and in again will fix it, possibly only if I'm in the same or a nearby chunk. I also found some more fire blocks in a nearby forest, and these were harmless too. I think I've also seen similar reports at least 1-2 versions ago. --82.69.54.207 21:32, 7 July 2012 (UTC)

Annoyances

a If you place a slab on a grass block (that has tall grass on it) from above (standing next to, looking down at where you are to place the slab), the game erases the grass and sets the block on the top half of the box. Common sense would say that the slab should replace the grass but be placed on the bottom half of the box. I assume this happens because the game uses the grass' bounding box to determine if the slab should be placed in the upper or lower half of the box. --5thHorseman 19:58, 5 July 2012 (UTC)

a If you place a block to make a wall and stand as close as possible to that wall, and then place a block, the game renders the block for a moment, then disappears.
 * I don't think this is a bug; you're placing a block in a space you're partially occupying, so the game tries to place it, but then removes it. This is nothing new and is certainly not a major bug. Please visit the Classifying bugs page and sign your comments with ~ . Downgrading and editing for clarity. --Keithicus420 18:40, 6 July 2012 (UTC)

a The following blocks do not burn (add more if I missed some): --93.106.71.228 12:18, 7 July 2012 (UTC)
 * Sign
 * Ladders
 * Crafting Table
 * Jukebox (would waste diamond)
 * Bed
 * Wooden Pressure Plate
 * Wooden Door
 * Note Block
 * Trapdoor
 * Chest (would be terrible if it did)
 * I'd like these to catch fire from a 'realism' point of view, but given some of these blocks' wide use in mechanisms I think it might be a grave error to change them. And if you don't change the pure wood ones - ladders, signs, doors, pressure plates in particular, what's the rationale for changing the others? Burning them in furnaces, I'd be a bit more liberal. --Simons Mith 19:17, 7 July 2012 (UTC)
 * Well I didn't expected everyone of them made able to catch fire, obviously. But ones that I really liked to burn are Sign,Ladders,Crafting Table,Bed,Wooden Door,Trapdoor. Some of them don't have critical function. Bed is destroyed by blast anyway. Doors can be bashed by zombies (or least some point could). Wooden Door has iron alternative. Maybe ladders and trapdoor should too (however trapdoor recipe isn't straightly compatible). House that has Wooden Door, if it's from stone, only door would be flammable, if it's wooden house, what protection would be left anyway if it burned down. --93.106.71.228 20:37, 7 July 2012 (UTC)

a Many times while underground (This is only where I have noticed it), many blocks may be represented by a stone block, and will revert to their true image and properties if hit, or something is placed upon them. For example, while walking across a stone floor, it is possible to hear the noises of walking across gravel, and if you strike the blocks at your feet, they will turn into gravel. Or placing a torch on a stone wall will suddenly turn the block it was placed upon into dirt or gravel. This causes problems as it can also occur with blocks such as ores. Meaning that one can mine a vein of coal ore, only to miss some that simply look like stone until struck. This raises concerns of the possibility of passing up diamond ores for the same reason (While I have not seen this occur, I have no reason to believe it could not). If say a dirt block were represented by a stone block (I have also never seen any block other than stone behave this way. I have never seen a dirt block turn to stone nor any block turn to any other, other than stone turning to other blocks), and one were to destroy this block, it would respond to tools the same way a stone block would (be broken quickly by a pick), but when destroyed, is instantly and briefly replaced by a dirt block, then the dirt block disappears leaving a dirt block entity. In addition, although the stone block shares most of its properties with normal stone blocks, walking on it will produce the sound of walking on the block it represents, the dirt sound in this case. If one were to begin destroying this stone block and then stop, however, the stone block is then replaced by a dirt block and then has all the properties of a dirt block. A detonating creeper will also reveal the true identities of the stone blocks around it. However, if say a gravel block were represented by a stone block, and a creeper detonates standing near it, it will use stone's value of blast resistance during the explosion, then turn to gravel afterwards, creating the appearance of gravel or dirt being unnaturally close to an explosion.

While it is true that it does not affect the gameplay much, it is still a bug.

a! Interface redrawing is slowed signifcantly by in-game lag. What happens is that whenever I am in a jungle and experiencing lag, I hit Esc to enter into the UI to swap the graphics from Fancy to Fast, but doing this very thing means that the UI is lagged very badly until the Fast graphics are actually enabled in the UI. If Mojang could at least separate the draw/redraw of the UI from the draw/redraw of the world rendering I would be able to at least swap to a different rendering mode much more easily. Additionally, if Mojang could come up with an interim fix for jungle biomes that limits the amount of lag they are allowed to force into the rendering of the jungle biome until Mojang get to fixing it in 1.4 that would be very helpful to people lagging in jungle biomes. BrickVoid 00:25, 6 July 2012 (UTC)
 * An update to this bug, the lag still seems to happen in jungle biomes but the client is now apparently capable of reducing it although the fact still remains that jungles cause lag under certain circumstances. To anyone else experiencing this lag in a world generated in a snapshot prior to this snapshot, the current 12w27a snapshot does still lag in the same manner if you load a world generated in a previous snapshot with jungle lag problems.  The lag the old snapshot generated may still cause the same lag, however, generating the same world seed with the new snapshot seems to cut down the jungle biome lag to almost nothing.  I've tested this with a seed I use a lot, and it would appear that a big lag problem at the moment seems to be jungle temples, I don't know if this is directly related to the temples themselves, however, the temporary workaround I found for the last snapshot still seems to work.  Go to the graphics option, and then switch from Fancy to Fast graphics.  Switching back to Fancy graphics also appears possible if sufficient time is given for the client to recover while in Fast graphics mode. BrickVoid 05:46, 6 July 2012 (UTC)
 * I've changed this to a major annoyance. It's not a bug but it is annoying. I split the interface annoyance away from the "jungle lag" issue. I have also altered the start of the report because of the split.


 * How is it possible that an actual bug that affects the interface is considered an annoyance? This is code which is bugged because it's not doing what it's intended to do, therefore I request that you upgrade this major annoyance of mine to a minor bug.  I've also slightly altered the start of the annoyance report:  I changed the ? to a . because it really isn't a question now. BrickVoid 21:26, 6 July 2012 (UTC)
