Sorry you're having issues!
Can you try to start your game in tracemode by going to 'settings' > 'troubleshooting' and checking the box 'enable debug trace'.
Then after the next time your game crashes restart the game and go back to the same place as before and click the button 'Open Trace File'. Then attach that file to a post here on the board, or email it to
support@ootpdevelopments.com and we'll look into the issue.
