SlimeKnights/TinkersConstruct#3030

This crash occurs when using:
Pokecube Revival 6.6.0
Pokecube Mobs 2.10.0
Pokecube Core 6.9.1
Thutcore 5.5.0

Rolling back to prior builds and the crash goes away
Using works:
Pokecube Revival 6.5.2
Pokecube Mobs 2.9.0
Pokecube Core 6.8.0
Thutcore 5.5.0

hmm, I wonder if that release went out before some of the internal changes in my code to fix exactly that from happening, as looking at it now that shouldn't be possible to occur.

If anything this crash will be fixed in the next release.

this crash should have been fixed in the latest beta releases.
