The Nintendo switch edition continuously corrupts game files in a way that they cannot be accessed again. I have made copies of worlds, restarted the console, and re-downloaded the game but it still corrupts files after about 25-30mb of space is taken up. My Nintendo switch has 11gb of free space as well so it is not a storage problem. Please address this soon, as I have played many hours on these worlds and I have found some unique world seeds.
