[testlive] [singleplayer] Furnace disappeared

so after loging off singleplayer game crashed and fatal error mesage poped up. after loging in the furnace was completly gone along with all the mats in it. It was in midle of producing iron bars with coal as fuel.
Also the production sound plays all the time when crafting station produces something regardless of that if the crafting station inventory is open or not. quite irritating.
