the fire icon in the furnace doesn't update after I save&quit and relogged in. This happens with lava buckets and so far only tested with smelting cobblestone and sand. Note that the save&quit happened while the smelting process was still happening.

What I expected to happen was...:
I expected the furnace's fuel indicator to be at the same level it was when I quit and saved, and I expected it to decrease at the same rate at it would normally when smelting one lava bucket's worth of items.

What actually happened was...:
the fuel level indicator was at full after I re-entered the game.
note that the fuel indicator didn't drop at all until the lava bucket is used up. The fuel indicator doesn't change until about the lava bucket's 100th item. at the 100th item it rapidly decreases to zero.
Steps to Reproduce:

1)begin smelting (only tested with cobblestone and sand) with a bucket of Lava in a furnace and a full stack of the chosen item. allow the fuel level indicator to drop enough to be partially depleted. make sure to place all items in the furnace by hand. take the bucket out of the furnace before quitting.
2)save and quit and enter game again. note i didn't quit out of the minecraft launcher (v. 1.3.9.)
3) the fuel indicator will be reset to full and will not show that the lava has been used at all. however, the lava will still be used for the normal 100 times. at the ~100th item, the fuel indicator will rapidly decrease to empty.
