---- Minecraft Crash Report ---

Server crashes at startup.
Please fix.

Woops, looks like I missed a letter! Though you shouldn't really be using it on servers yet :p. (Though it's not relevant to servers, it'll happen in singleplayer too) I'll have a fix up in a few days, for now I'd suggest to just stick with b6. It's happening due to having a mod which adds 'cropRice'
