When the power cord is unplugged mid-game, the world actively being played on deletes itself un-retrievably.

While playing my world, I paused the game to deal with a disturbance. Doing so, I knocked the power cord loose. When I rebooted the Xbox and the game, the world was absent from both the world list and the storage section of my settings. During the accident I was signed in to my account, and the game automatically signs me in and “syncs” my worlds every time I boot it up. This syncing does nothing and, as far as I am aware, my world (and the tens of hours I had spent since I had last copied it) were gone. Since the edition I was playing makes no backups naturally, I dread to think of the foolish souls who could so easily loose everything, and not have a copy to fall back on.
