0.6.0 Furnace Bug

When you start cooking in a furnace and then quit a map and re-open it, the furnace fire/cooking animation is stuck on.

What I expected to happen was...:
Normally it continues cooking from the time I left the map and finishes and turns off.

What actually happened was...:
I came back to the map and the furnace was still going. I opened the furnace, the coal was gone, there was no sign of the cooking fire in-between the two left blocks. Yet when i closed the furnace (and every time I've gone into the map since) the fire animation on the front still burns. (also it added a load animation on the item I'm smelting, but the image is of the "x" button in the top right corner of the inventory)

Steps to Reproduce:
1. Place a furnace
2. Start a stack of anything smelting
3. Close the map/restart the app (Idk which one I did)
4. Open the map and check the furnace
