I joined the Beta for this last update, I received a noticed from the Xbox insider hub to install this update I need to uninstall the Beta game first and reinstall it. But all my saved games were deleted because I uninstall the game and this game don't save my worlds on my documents folder.4 years for nothing....
There is any way to restore my Saved worlds?
