Logging out of the game with one or more furnaces in use stalls the furnace upon restarting the game and no further items will be processed.
Steps to reproduce:
1] Put fuel and material into furnace
2] Watch furnace process material
3] Quit game
4] Restart game
5] Examine furnace
Expected: furnace to continue processing raw material
Actual: furnace does not continue processing raw material

Furnaces Stop when Re-entering World

Confirmed for me. Fuel continues to burn (including animation and removal of fuel), but the material does not process (no animation on that, nor anything moving to the finished slot)
