Title: Fixed random crashing around NPCs

I caught one crash that happens around NPCs due to not checking the
return of mon_at.

I just wish I understood the map system. There are still problems that
appear to be due to not regenerating maps after crashes which force the
user to delete the save folder to fix the problem.
