i was just testing the wet sponge block in furnace (to get the normal sponge) then i saw this bug.
Furnace in village, randomly turns when lit
Furnaces face south when cooking
Furnace changes orientation on use
When Smelting Something the furnace faces North
Furnaces turn to the left when put to use
Furnace rotates once fired up
When placing a pumpkin, its face does not face the player.
