Gone, Reduced to atoms

Found out a possible reason for why this happened. On an xbox, any amount of profiles can be signed in at one time, allowing for two people to either play together or for game sharing, I happened to have a separate profile signed in as well as my own and played 2 runs of co-op with my siblings. Unfortunately, the game doesn’t check for multiplayer data based on the active profile. It checks for every signed in profile. If more than one profile is detected without an active player and the player commits to an online action (like doing a daily run or saving), The save data is erased because the game (for some reason) can’t differentiate between the profiles.
