I've been experiencing crashes when trying to replace my flint pickaxe with a copper head. I was able to replace the parts (both the handles and heads) on my mattock, shovel, and hatchet, but the pickaxe crashes the second I place the copper head into the forge.

Good ol' picture never fails me

Jeez I'm such a doof. Thought I had the right version of TCon... but obviously not.

Great mod, keep up the great work! :-D
