My xbox one failed after over a year, received a new one. I loaded minecraft no problem, when I pressed play game it would not sync...said my previous xbox was still syncing. I could either try again (which did nothing) or revert to last save...which I eventually did. And BOOM a large bulk of my sons maps are gone. He had saved them and used them repeatedly over the last few months. ( I also use an external but those maps save on the cloud) Called Microsoft and didn't get an answer...HELP PLEASE!!! Are the maps gone forever or can they be retrieved? Thanks everyone!
