Crashing/System

Bugs

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

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

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)

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 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)

[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)

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

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)

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)

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)

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