Crashing/system

Bugs

WindowsUpon logging into my own Minecraft server, the game runs for about 5 seconds then Minecraft abruptly closes with no error log. 68.10.66.162 22:24, 4 December 2012 (UTC)Len 68.10.66.162

[!!] When trying to open a Minecraft World, it crashes.

Is Modded: Very likely; Jar signature invalidated. java.lang.NoClassDefFoundError: com/pclewis/mcpatcher/mod/RenderPassAPI. Definitely modded using the McPatcher. Please, use a clean minecraft.jar before posting errors. Force updating will solve this. If not, delete the .minecraft folder (keeping worlds of course) and let it be remade. #trigger_hurt(I|T|C) Check out my project! 18:24, 12 December 2012 (UTC)

Gameplay

Bugs

[X] Items, but not mob type entities, will bounce off of any block that has a visible hitbox where there is actually empty space (NOT Slabs!!) if they are thrown onto such empty space. Can easily be recreated by simply tossing an item into a cauldron. The item in question bounces about, usually bouncing out of whatever was supposed to hold it. #trigger_hurt(I|T|C) Check out my project! 12:36, 3 December 2012 (UTC)

when you deploy water in a dispenser the bucket left behind will not suck it back up.

Please sign your posts, use four tildes (~~~~), and don't forget the bug tag {{bl}} in front when classifying bugs, you do not need an account to do so. As far as this goes, dispensers seem to be behaving normally. I have a "hot tub" on one of my creative worlds, seems to be working just fine as it is retracting the water as normal. #trigger_hurt(I|T|C) Check out my project! 17:23, 6 December 2012 (UTC)

[X] Item Frames still get destroyed by creeper explosions when mobGriefing gamerule is set to false

Annoyances

[A] Dropping or picking up an object while breaking a block resets the cracks

[A] Related to this, when breaking a block while holding the type of block you are breaking, when you pick it up, the next block you break will have its cracks reset; this is most obvious when holding dirt to break dirt. -- Liquid Spark 06:32, 12 December 2012 (UTC)

World generator

Bugs

World will not generate when first started, Have to restart to start generation!

Mobs/NPCs

Bugs

[X] Animal types (sheeps, cows, etc.) Push other animal types through walls/fences, or they walk through them on their own. 76.181.157.21 06:30, 11 December 2012 (UTC)

Annoyances

I have noticed this as well, but only on single player. Doesn't seem to happen on multiplayer. Very annoying, since I have all of my sheep in a large fenced area, and almost every time I load the world I need to get some more wheat to lead them back inside. #trigger_hurt(I|T|C) Check out my project! 18:26, 12 December 2012 (UTC)
