I was trying to load my world, which I made back in 2012 on Xbox 360 and still build on it to this day, but everytime I tried loading the world, it would say "updating packs 1 of 2" or something, and when it would finish, it would kick me back to the world selection menu and not let me load anything. I tried resetting the game, that didn't work. Thats when I hard resetted my Xbox One. I did that and when I loaded the game, the world was gone. But I luckily made a copy of the world before that, but the same would happen to that and now both copies are gone, so I decided to opt out of beta and had to reinstall the game in hooes that would fix it, but it didn't!!!!
