I was cooking Iron in blast furnace, app kicked me out and I lost my iron

I put iron in my blast full nave with a block of coal because I had a whole stack they I took some other iron I haven't "cooked" yet and I put it in the other furnace then today I got the iron and put it in my inventory they I put mutton in the smoker and then it glitched it kicked me out of the game. Then when I joined again I still have the raw mutton in my inventory but there was still mutton in the smoker I got double my items but I lost my iron, I know it's not much but I really need to make a anvil and there's like no caves anywhere near me so I can't get anymore without travel a LOT. Thank you for reading and I hope you fix this soon.
