As it says "continue" continuing from when it says "welcome to beta 1.16.0.57, here's what's new", if you press Continue, the game proceeds to crash and you can't load up your game. It has also done this for my sister. It only possible, if you press Continue fast enough, then you can access the screen where it says "marketplace" and "play" however it crashes immediately, so I can't access my worlds at all.
