Crash when crafting crystal pickaxe. Running MC 1.10.2, The simple life 2 modpack 1.4 toast version.
This crash couldnt recover, server would not start, didnt have mc edit to fix at the time so had to restore a backup world. Any ideas what caused this or what to do to fix? Thanks for your help

Don't use crystals without stats. That pack is bad about that.

Also, unsupported version.
