I was playing the Stoneblock modpack, and for no reason, I thought hitting the Sort inventory key (I believe from InventorySorter) would work and help sort the patterns.

Turns out, it was a bad idea. It took me 4 tries to actually join my world again. Is this the mod's issue or is the blame on InventorySorter?

can you please post a crash log (create a new creative world if you need to)
