The game shuts down during game play. The progress does not save. Prior to the crush glitches appear, for example placed sand blocks don't fall for 1-2 seconds. I have 3 worlds. The above issue Applies to only 1 of my worlds - the biggest one, around 600Mbs in size. The other 3 function fine. Tried restarting the game, tried restarting the phone, deleted the app, then reinstalled it - no effect, the problem does not resolve.
