I was using the Calcinator to create Minium Dust. I put 8 Diamonds in the input slot and some Coal in the fuel slot. When I tried to take the Minium Dust out of the Calcinator, my game crashed with this report:

EE3 Version: 0.2.433.
Forge Version: 10.13.2.1307

You should report this to the devs of BluePower. BluePower is not checking the size of the inventory when a crafting event is called and (probably) assumes it's a 3x3.

Ok. I just submitted it to the BluePower Github.
