June 5 update problem with furnace. Can't put in fuel.

When I tried to cook clay in furnace you could put clay in, but not the coal for fuel. Then when I tried to take clay back out it would not work. Tried with other materials they didn't work either. In order to to try again I built another furnace as well as break one.

What I expected to happen was...:
Make materials that could be used for other stuff. Like it did before update.

What actually happened was...:
Listed above.

Steps to Reproduce:
1. Click on furnace
2. Put in materials and try to put in fuel
3. Try to remove materials
