I get this message "No altar on this level" as a prompt sometimes and when i click OK, the game just crashes. Both times i THINK I was trying a precrowning with a chaotic altar.
Same error before saved file ceasing to load. Though I didn't do much other than try to climb a staircase away from a level containing a neutral altar (I was a DwPl) in da puppy cave. Attached my error log.
