As most of you already know from another thread, I recently got a new XB1 for my birthday (and if you didn't, well, now you know). So far it's great with the small caveat that I have to reinstall nearly all of my games, despite already having them installed and up to date on an external. Minecraft XB1E, however, seems to be in a world all its own - for some reason, the game didn't need to reinstall/update, but I can't access my previously saved worlds from my brother's XB1. They appear on the main menu, but whenever I try to load it, I get a message saying that it needs to be synced before playing. I let it sync, but unlike when a game gets a mini-update and syncs, this is incredibly slow. I can wait upwards of 30 min. and it never finishes. I keep getting an error message saying that it was unable to finish. Since it can't finish, I can't access my previously saved worlds. The highest I've been able to get it to is 95%.
Any idea why it does this or how I can get it to fully sync properly?
