Game stopped working

The game was great up until I got my werewolf morty to level 39. Now every time he levels up to level 40 the game closes out. I searched the web to see if anyone had similar problems but wasnt able to find anything, then I tried to fine a way to contact the developers to report a problem but wasnt able to find that either. :( bummer
