As long as I win challenges the game seems to be working fine. I started the game over and am just now getting to the King battle. I tried it with and without a booster, but the game locks up right after I lose the fight either way, so there's no quest in the underworld available. I restarted the game and synced the save up to the cloud. This is where I'll stop for the day, since there's no way around this crash. Thanks again for all your hard work.
