I haven't seen this one posted anywhere yet. I decided to let Roehm sleep outside near Swart's camp, and I get a message that I'm attacked while asleep. The battle screen comes up, but there's no enemy shown. If I do something, the game crashes out with this message:
in "room299.asc", line 598
Error: AnimateCharacter: invalid loop number specified
If I just sit there and wait, I get this instead:
in "combat.asc", line 200
from "room299.asc", line 425
Error: AnimateCharacter: invalid loop number specified
It seems to be the same error, though. I'm attaching a saved game called "stuff". Because being attacked during sleep seems to be random, you may have to restore and sleep a few times before the attack kicks in.
