 * One, "Craching" should be crashing, two, you are holding TNT in your hand, could you describe what you were doing, three, it is probably a good idea to do what it says at the top of the crash and include the extended file. Ps, don't wory if it crashes, your world is likely fine, just always make backups.  01:52, 15 December 2012 (UTC)

}} And this is from the saved file: undefined Type: Integrated Server (map_client.txt) Is Modded: Probably not. Jar signature remains and both client + server brands are untouched. }} My world was made of the weird piston block 33:6, which may have caused the crash.

Gameplay
Bugs a Unbreaking can be put on armor in survival mode, but has no effect on the armor. -- 19:53, 13 December 2012 (UTC) undefined Efficiency on a pick does not have any effect on dirt.
 * I think efficiency affects "proper" tool, which would be shovel. -- 14:07, 14 December 2012 (UTC)
 * Actually, it does. If you have a pickaxe with efficiency on it, it will break ANYTHING faster, except the blocks it is not allowed to break. ( 14:10, 14 December 2012 (UTC)
 * Just tested for diamond pickaxe lvl 4 eff, didn't notice any speed difference comparing to un-enchanted one. Used it to break dirt/grass blocks. And why this page headline says 12w50a when link I clicked showed 12w50b? -- 14:31, 14 December 2012 (UTC)

Annoyances undefined Wooden slabs are suddenly hard to mine, it takes about as long as mining stone by hand and dont drop wooden slabs, even when mined by axe. Edit: And have to be mined by pickaxe.

Mobs/NPCs
Bugs undefined Mobs are not able to change the block niveau. When they get to a height difference of one block they mostly walk in circles. 10:47, 16 December 2012 (UTC)

In-game interfaces/HUD
Bugs aOccasionally while mining, the HUD will restate what tool you are using. a          Actually, at the moment, that's caused by durability changes. You're likely using an unbreaking pickaxe, if it's on occasion.
