Putting coal into a furnace crashes the game.

Putting coal into a furnace crashes the game.

What I expected to happen was...:
Coal would be put into the furnace, cooking the raw porkchop I had in there

What actually happened was...:
The game suddenly crashed.

Steps to Reproduce:
1. Put something to cook in a furnace (I used porkchop)
2. Put coal into the fuel slot
3. Crash!!

I also found out that just putting coal into a furnace crashes too.
