Hello! I tried to craft a chisel in Multiplayer and I could not take out out to put it in to my inventory. Eventually I tried Shift Clicking it, it ended up in the slot in my hand and it crashed my client. Log: http://paste.ee/p/ZwdNK

The mod is not installed on the server.

Oh . . . Must have accidentally left the 1.7.10 version on the server side . . . Thank you for the quick response, sorry for my mistake ^_^
