I'll try replaying it, taking into account that only joined and unupgraded skeletons, etc., are used; Cyrus will appear, and I'll run away, lol. But I wouldn't want to remove the mod right now because I haven't finished a few single-player maps where heroes from the campaigns are used, like Kujin, Arantir, and Ornella. If it doesn't help, I'll remove it.
