Observed behaviour

Attempted to place myself in a normal, empty, minecraft cauldron that was heated by a soul campfire to produce blood to put in a bottle. As soon as I took damage, some blood appeared in the cauldron, and the game crashed. Subsequent attempts to load the game also crashed. Deleting the cauldron via a world editor (Amulet) allowed me to load the save once again.

@RyozuK please attach the crashlog, not the debug log

Sorry, was dead tired and didn't pay enough attention.

Having gotten some sleep, and looking at this log however, I'm suspecting it's actually an issue with Ars Nouveau instead.
