When you make charcoal and put it in a chest it disappears when you open up the world. It also does the same with damaged diamond tools. Not sure if it works with other items.

What I expected to happen was...:
The item would stay in the chest and not disappear

What actually happened was...:
The charcoal and damaged tools disappeared

Steps to Reproduce:
1. Make charcoal
2. Stick in chest
3. Quit the world
4. Reload the world
5. Check the chest
