Describe problem (what you were doing / what happened): When using the pestle on the mortar to create a spell receive an overlay message saying, "Recipe found but missing rare materials mixin'". Nothing else happens.

Crash log (if any): No error in the log

Well... Have you inserted a rare material like an old root?

Oh... mb, I missed that part in tablet and misunderstood the error. Yeah that worked. Thanks for the quick reply!
