Chisel is crashing, contact the mod author and remove it

unluckly we can't remove the mod, the world wont start without it...

any idea how to track down the issue and fix it? :/

version: Chisel-2.9.5.11

Crashlog from thread: http://pastebin.com/y3wPtbNm

I don't even know. Disable the PresentChests in the meantime.
