I have had this happen a few times now-- basically the player enters into a town with bandits, and instead of spawning my army, there is an army of the player character. Sounds cool, but the dopplegangers can't move, won't take orders, and don't fight. Moreover, the "bandits" are my army and companions. It seems the problem is that there actually aren't any bandits in the town; in fact the normal town menu options are available. For example, if I select "go to town center" I can walk through town with no bandits, and when I exit out the problem is resolved and there are no bandits. If this happens again I will keep the save game file and post here.
