Additional context
Only just started world and played for a few hours on 1.7. Got as far as being able to make iron ingots and started a vanilla farm and a squid farm. Trying to load world after updating to 1.8 creates crash, crash report in above hastebin log.

Please revert to 1.7, I'm working on a fix.

Just an FYI, I'm able to load my world but get this same error when exiting compact machines.

Might be an issue with latest version of Forge: http://www.minecraftforge.net/forum/topic/66708-operand-stack-overflow/?tab=comments#comment-320368
