Game is not saving correctly when exiting world.
The load screen were you choose which created world to enter shows the correct picture from were you exited the game. But, when you reenter the world, an old saved version is loaded, not the version were you exited the game.
It always goes back to the same old save, loosing and changes that were made since that save.
Using Xbox One Live.
