I'm not sure if it's just one, or all of my kegs, and not every interaction crashes my game, but I'm able to reliably crash the game now. Specifically I try to put sugar cane in the keg.
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000380
Update: the game fully deleted a keg (after it crashed right after saving the game) and now it no longer crashes when I interact with the keg. One of the problems could have been somehow my bee house was overlapping the keg's squares. Idk what happened but it's good now.
