When I loaded up Minecraft bedrock edition (better together version, Xbox one), the first thing I did was try to create a copy of one of my worlds as a friend warned me that his save became corrupted today.. Mid back-up, my game restarted and I am no longer able to load up the world. It seems corrupted. I get an error message, 'Failed to sync world data - This world is not fully synced or has been corrupted. Try playing the world on a console where it's in a good state and try migrating it again'. Both the original save file and the back up are affected. I've been in touch with Xbox support and I have tried resetting my console (keeping games and apps). I have also tried deleting my account from my console and redownloading it. However the desired save files still fail to sync. What is going on? Also more save files have met the same fate since I first encountered this issue about a week ago when I first emailed Mojang. Please help! I'm losing worlds left, right and centre, some of which I've put hundreds of hours into!
