Update by [Mojang] Mega_Spud (Jay Wells):
- Place cobblestone into a fuelled furnace (this gets smelted into Stone)
- Take the Stone from the furnace output, and try and smelt that again
The stone obtained from step one cannot be smelted into smooth stone (because it has a damage value of 32767).
The player should be able to smelt stone into smooth stone without issue.
Screenshots/Videos attached: Yes
Using a furnace, Stone does not cook to Smooth Stone in this version.
I place Stone in the input slot of the furnace, and coal (or other fuel) in the fuel slot, with the result that the progress bar does not move.
I expected Smooth Stone to result from a smelting operation. But instead, no smelting occurs, and no fuel is expended.
I have attached an image that shows what happens when Stone is inserted into a furnace, along with valid fuel.
The Stone in question was obtained by smelting Cobblestone.
Oddly enough, while investigating this further, I found that Stone obtained through Silk Touch does not stack with Stone obtained through smelting Cobblestone!
