crash report: https://mclo.gs/eOJD3bt

It worked on the last release but failed upon updating

Looks like the fix I put in for #30 is causing problems here. I originally tested with Thaumic Wands and not Polymancy as well. Although, looking over the fix I did again, I made a poor decision there that I'm surprised didn't cause problems for me in testing.

Please try 1.0.2 when you get a chance. I couldn't reproduce this crash, but I tried a new approach for the fix that hopefully won't cause problems like the last one did.
