Crashing/System

Bugs

[!!] When I Connect To 12w30a server/lan with 12w30b sometimes crash the client!!

  • Why would you try to connect to one unreleased version of the game with another, newer unreleased version of the game? This is not a bug. You are not using the software in the manner in which it is intended to be used. --5thHorseman 15:37, 23 July 2012 (UTC)
  • Some people don't have access to the server though. Like for exmple, my brother tried connecting to my server (which I hadn't bothered to update yet, he woke up before I did) and got disconnected. How is he supposed to change that if he has no control of the server? The simple answer is to either use an older snapshot (why should he switch to a buggier version?) or just wait who knows how long till the server administrator updates it. --Frostyfrog 16:59, 23 July 2012 (UTC)
  • But it's not a bug. There is no promised or expected backwards comparability between released versions of Minecraft. Why would you expect it in snapshots? --5thHorseman 17:55, 23 July 2012 (UTC)

Template:Bl! When I come back from the Nether, no chunks load and I fall out of the world. Sometimes I die, and everything reloads normally, but sometimes I keep falling forever and and have to restart the game.

[!!] Got the following crash when switchching from creative to survival in a flat world SSP

Annoyances

[A] [MP] When connecting to a previous snapshot version's server, I tested the old portal bug in the nether (when it'd throw you to an invalid position in the overworld). Now I am unable to play on this server in any of the recent versions as when I log in I get an 'Invalid Position' message and kicked. I have marked this is a minor annoyance because no-one is probably in the same situation. --CallumTennant

  • Just delete your player.dat file in players\[thefile].dat. --88.194.198.246 13:41, 23 July 2012 (UTC)
  • I have no control over the server files, though. --CallumTennant

Fixed/Skipped

Gameplay

Bugs

[X] Mobs may spawn inside jungle biome leaves. See: [[1]] CallumTennant

[X] macOS 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, and he tried to fix it this snapshot but it still doesn't work. CTRL-V does work on a Mac, but it is unintuitive for Mac users. TorchicBlaziken 21:14, 28 June 2012 (UTC)

[MP] When teleporting to the nether the server lags. A noticeable spike on the server client appears also. Screenshot: [[2]]

Annoyances

[A!] Mobs spawn on non-natural occurring blocks Djerun 12:47, 23 July 2012 (UTC)

  • See discussion talk:Known_bugs/Version_12w27a#Mobs spawning on 'non-natural' blocks --80.134.11.177 12:52, 23 July 2012 (UTC)

[A] Tree leaves grow through glass (without breaking glass) - see screenshot at http://imgur.com/wq6ha. Hopefully the fix for this doesn't involve breaking the glass (instead the leaves shouldn't grow through glass). --Whoisvaibhav 15:19, 23 July 2012 (UTC)

[A] [Cr] The bug where you can't fly as fast through water and lava was fixed, but cobwebs still slow you down while flying in Creative mode. TorchicBlaziken 20:07, 14 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)
  • When looking at a tall grass block and attempting to place redstone dust on it it will place it on the closest adjacent block to it.

Fixed/Skipped

Blocks

Bugs

[X] Piston sometimes expands and leaves the original wood part too. (Screenshot) -- Mustek 12:21, 23 July 2012 (UTC)

  • Huh. Can't reproduce. Does it always happen or just sometimes? — Mojang AB logo Dinnerbone(T) 12:28, 23 July 2012 (UTC)
  • It did happen a lot, it's SMP, forgot to mention that. If you want, I can send you the ip. -- Mustek 13:02, 23 July 2012 (UTC)

[X] Standing middle of block that piston pushes sideways, makes you fall through pushed block. --88.194.198.246 13:04, 23 July 2012 (UTC)

[X] Double slabs cannot be placed if the last slab placed of the two will touch another block on its top or bottom side. http://i.imgur.com/Tac3b.png and http://i.imgur.com/0zvsc.png are examples where the second slab cannot be placed to create a double slab. ~Cm283 16:04, 23 July 2012 (UTC)

[X] Arrows shot at the top half of a door will float once the door is opened. However, arrows shot at the bottom half will either fly forward or drop when the door is opened (depends on which part of the door you hit)

[X] If you place a slab on top of an ice block, you will still slide when walking on the slab.

[X] Vines, tall grass, or lily pads held in third-person (F5) appear gray.

Annoyances

[A] Breaking a block underwater doesn't show the breaking animation when standing above water

[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 13:26, 23 July 2012 (UTC)

[A!] [MP] Cannot interact with chests and doors when holding an item. (Only tested in multiplayer) (Only two blocks tested)

  • 100% sure you and the server are on 30b and not 30a? — Mojang AB logo Dinnerbone(T) 12:30, 23 July 2012 (UTC)
  • Sorry, I was in 12w30a, but I just tested in 30b, and it didn't happen.

  • (struck trough since non-bug) --80.134.11.177 12:50, 23 July 2012 (UTC)

[A] 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)

  • Not a Bug. Set to annoyance --YellowMiner 17:43, 23 July 2012 (UTC)

[A] When collecting Mushroom blocks with Silk Touch it will not preserve the damage value. TorchicBlaziken 23:49, 2 June 2012 (UTC)

[A] When placing Mushroom blocks of a damage value greater than 0, it will revert to 0 upon placing. This used to happen with Monster Eggs, before they were tweaked in 12w17a to prepare them for inclusion in the Creative Mode inventory. This should be changed because the damage values of mushroom blocks are now available using cheats. TorchicBlaziken 23:59, 2 June 2012 (UTC)

Fixed/Skipped

Items

Bugs

[X] Thrown eggs sometimes drop right in front of you when thrown, but chickens spawn where it was supposed to go. -- Mustek 12:22, 23 July 2012 (UTC)

[X] Rapidly splitting and placing stacks in 4x4 craft in creative causes a minor duplication. -- TehRainbowGuy 16:01, 23 July 2012 (UTC)

Annoyances

[A!] Can not create more than one new line and cannot begin a line with spaces when entering text on the Book and Quill item. This was previously a feature when the item was first released. -- 50.53.152.13 16:20, 23 July 2012 (UTC)

Fixed/Skipped

World Generator

Bugs

[X] Sometimes an empty river spawns in a desert (like https://p.twimg.com/AyfR11eCAAEzc42.png:large)

  • Nearly dried out because too less water flow in the desert ? More a feature than a bug. --80.134.11.177 12:54, 23 July 2012 (UTC)
  • I dont think this is a Bug... I hope its a feature
  • Okay how about this? http://imgur.com/ZgSVZ
    • I like it tooooo
  • I think this happens because it's loading a river biome on a layer higher than 63. Water will only generate in a river or ocean at level 63 or below, I think.

[X] Chunks seem to load very slowly, and while standing still some seem not to load at all until the player starts to move close to them. Pressing Escape to go to the in-game menu causes the chunks to start loading rapidly (really a more "normal" speed). Returning to the game again causes them to slow again. This was tested in single player. --220.233.85.220 13:44, 23 July 2012 (UTC)

[X] Just like abandoned mineshafts were before the floors were implemented, strongholds generate weirdly when they cross a ravine. The seed -623160645725253637 is a good example of this with a stronghold in a hole close to spawn which crosses an underground ravine. TorchicBlaziken 22:00, 4 May 2012 (UTC)

[!] OK I had this as a major annoyance in 12w26a (and seen it at least from 24a) and still goes, but (a) it got ignored (as it still goes) and (b) it can be considered major because if it happens, you are stuck in the map and have to quit. Download my map. my map Directly in front of the player is a cave. Go straight. Try to go down. BOOM! A whole chunk disappears and seems you can drop down to oblivion. You cannot drop easily though, because the player is stuck in some invisible tile or something (no suffocation). You can go down sometimes with some cursor-key jerking. I have dug around and found that water and lava does not drop in there. Mobs CAN drop in there including myself. Happens with w26, but also w25 and w24 too. Don't know if it goes further back. Note, I have NO lag whatsoever (i5, 8GB RAM, nv570) and game does not crash. Just this issue. It MAY happen in other areas too. --NLS

  • I noticed one thing. I touched this "void" chunk, got stuck and... saved. When I reloaded it was fixed. I don't know what would happen if I saved while stuck where a solid block should be. Still, it is clearly a bug.

Mobs/NPCs/Animals

Bugs

[X] Mobs/Animals can push each other through wall, then they seemingly appear where they actually aren't. You can boost this effect, by making small quarters, on animals wielding wheat, and on mobs aggravating them. Maybe it's caused by pushing speed value added after animals/mobs speed value has been clamped by walls, when pushing speed value should've been added before clamping. --88.194.198.246 13:01, 23 July 2012 (UTC)

[X] Feeding pigs wheat does not show any hearts. Still breed though. Only tested pigs on SMP. -- Hazado22

Graphical/Lighting

Bugs

[X] Stair block does not block light correctly. Tested smooth on/off csp and cmp. (more info on [edit]) --88.194.198.246 13:07, 23 July 2012 (UTC)

  • do you have a 12w30b screenshot?
  • I just won't upload new screenshots for every version if bug is still there. Just recreate and take screenshot if you want. --88.194.198.246 13:22, 23 July 2012 (UTC)
  • This wiki is for new bugs with the current snapshot, not existing bugs. They are well aware of the lighting glitches...--Arcooke 14:05, 23 July 2012 (UTC)
  • I thought it was for all bugs in the current snapshot? Many many bugs from previous snapshots have been put into each wiki page as a new snapshot comes out. --5thHorseman 15:53, 23 July 2012 (UTC)

[X] After logging in to a 12w30b server, one of my double chests only rendered the right side as a single chest. The left side had the hitbox/collision box and it could be opened normally. Re-logging fixed it. (screenshot) Masa 13:41, 23 July 2012 (UTC)

[X] Fishing lines will appear to the left of the fishing rod when in a Field of View higher than '69' or 'Normal'. CallumTennant

[X] The lighting bug still exists (random dark places in map) http://img826.imageshack.us/img826/2488/afbbb5f011da4c3bb6bf919.png CallumTennant

Annoyances

[A] Other player's fishing line is still bit off. --88.194.198.246 13:51, 23 July 2012 (UTC)

[A] When retracting fishlines, they just disappear instead of 'reeling it in' -- Mustek 14:03, 23 July 2012 (UTC)

Fixed/Skipped

Sounds

Bugs

[X] Fire extinguish sound does not always play. Sometimes hitting the fire plays the hit sound of the block below the fire/in fire. (has been like this since the change in the multi-/single player stuff I think) Masa 13:58, 23 July 2012 (UTC)

  • I was unable to reproduce. Also, I don't know if this is a bug, but when I extinguish a fire it plays the extinguish sound twice. CallumTennant
  • It seems to mostly happen in SMP. I just re-checked, it worked in SSP but not in SMP when lighting some netherrack on fire and putting it out. It may have something to do with unloading/loading chunks(?), because it works sometimes and then again sometimes it doesn't when I come back and try again. Masa 16:42, 23 July 2012 (UTC)

Annoyances

[A] After logging in to a server, the walking sound does not play while the server is under higher load (sending stuff to the client etc?). Other sounds seem to work though. (I used top in a Linux box to watch the CPU load while logging in from another PC. The load was ~60-123% some 10 seconds after logging in, and then it dropped to around 30%, which it was normally while I was logged in. The sound started playing when it dropped to around the 30% level.) Also, the walking sound does lag and hop occasionally after that too, according to server load it seems. Masa 13:58, 23 July 2012 (UTC)

Chat/Commands

Bugs

Annoyances

[A] /gamemode on yourself produces 2 "Your game mode…" messages – xPaw at 13:19, 23 July 2012 (UTC)

[A] Server /give command can only give 64 at a time. Can be remedied by using the Up button in chat but time-consuming in some instances Elite6809 (talk) 12:25, 23 July 2012 (UTC)

[A] Server /give command, if giving items to yourself, requires you to type out your full name over and over Elite6809 (talk)

[A] Using /tp [player] [x] [y] [z] with negative values are unintuitive for some players. They look F3 menu, see -33.5, they write -33. Don't dare fixing this by subtracting 1 if number is negative, then there will be non-teleportable locations. Just add the decimals, will you, please. --88.194.198.246 13:20, 23 July 2012 (UTC)

  • Where is the annoyance since you can use decimals now ? See the changelog One can now use decimals when /tp'ing to specific coordinates. --80.134.11.177 15:04, 23 July 2012 (UTC)

Menus

Bugs

Annoyances

[A!] While Playing, if you press Mouse 4 or 5(Keys often bound for push to talk in voice chat softwares) this will unlock the cursor, stopping you and making the game menu appear. I consider this major since being immobilized temporary in SMP is dangerous, even more in hardcore. --Algent 12:19, 23 July 2012 (UTC)

Fixed/Skipped

In-Game Interfaces/HUD

Bugs

[X] In the Creative inventory, the right-most slot in the hotbar in the inventory overlay on the Survival tab is different than on all other tabs. To pinpoint the offending pixel more, compare the top right pixel in those tabs. It shouldn't be as bright as the pixels directly underneath it. Redstonehelper 12:22, 23 July 2012 (UTC)

[X] When traveling between dimensions, the "Downloading Terrain" screen appears instead of the "Entering/Leaving the Nether/End" screen we know and love, since singleplayer is merged with multiplayer. Because of this, the sound effect that plays when using a portal does not play, either. There is no reason for it to say "Downloading Terrain" when it could just use the old screen. TorchicBlaziken 23:54, 7 July 2012 (UTC)

[X] You can't enchant anything between 21-29 levels with 15 bookcases. - ScreenshotxPaw at 13:23, 23 July 2012 (UTC)

  • You don't have 30 points, just 26 according to your screenshot. --80.134.11.177 14:56, 23 July 2012 (UTC)
  • I think he's trying to get the enchantment table to give him an option that takes 21-29 (ie, 26). It's giving him 20 or less and occasionally 30. Getting 30 proves that he has enough bookcases and should get (many) options in the 20s. --5thHorseman 15:52, 23 July 2012 (UTC)

Language/Text Files

Bugs

[X] In Pirate language setting, Ender Chests are labelled as "Tallone's Coffer" instead of "Tall One's Coffer" 70.15.197.133 13:58, 23 July 2012 (UTC)

[X] When getting shot on multiplayer by a fireball thrown by a dispenser, it says "<playername> was shot by Herobrine."

  • Probably just a little easter egg.173.69.40.23 17:23, 23 July 2012 (UTC)

Annoyances

[A] Wheat Seeds are just called "Seeds" even though specific variants of many other items and blocks (such as saplings, wood, and stone bricks) are being given specific names for 1.3. TorchicBlaziken 17:54, 16 July 2012 (UTC)

  • Agreed, but 'Grain' would be a better name for them anyway. --82.69.54.207 16:15, 23 July 2012 (UTC)
