Well, suddenly move_character did not work. The $%^#$&* ptolly general's name is not a short one, either. "Character not found", was the reply. Really?! I spelled his bleeding name at least 10 times - correctly.
I tried another battle tactic. I sent my entire melee army out so that the AI could not get stuck in a weird position (trying to get to a point below the city walls). I killed many enemies and they were starting to rout - CTD. I am beyond frustrated. THIS is a show stopper. I am out of ideas. Alexandreia MUST be the problem. No other battle has caused any CTDs so far. Only Alexandreia.
