Cooking Stops

I had logged out before updating after I started some pork cooking. When I logged in after updating. the pork was still in the furnaces but wasn't cooking. The coal was being used but not cooked porkchops were being made. I took the pork out and put it back in and it began cooking again.

I then tested to see if it would do this when I go to the nether and come back. The bug comes back when comeing to and from the nether. Wasted about 5 coal before I noticed the bug.
