Hi.

I have a bug report. This is actually kind of major since pretty houses could use logs. The bug is, trying to place any wood log will cause a game crash. I've tried with Oak Wood only. Placing a log causes a game freeze and then the game crashes after a few seconds, resulting in this error:

---- Minecraft Crash Report ----

Also, the block and water rendering engine was JUST FINE. It's messed up completely after the 14w25a snapshot. I'm afraid I can't send a picture because...well, the game crashes if I try to place a log.
