Hi there! I was trying to use the vanilla furnace, and had this mod installed. It crashed twice when I placed coal in it. So to test, I removed your mod, and now it's not crashing.

Let me know if you need any further information; hope I'm not being a bother.

Well the game just crashed again so it's entirely possible the crash wasn't caused by your mod at all, and I apologize.
