I have an xbox series x and have a disk of the dead space remake. I had removed the disk like a month ago to put in something else and when i put the disk back in today, all my saves are gone. The game started like i never owned it, but all my achievements are still there. Im on my second play through with new game plus, and now i have nothing. Please help, i unplugged my xbox twice and reset my tv. Idk what else to do, im devastated
