Was playing the 1813 scenario head to head and De Wrede of Bavaria changed sides. Next turn I noticed that there were two corps for De Wrede - one French in Munchen and another one Coalition of the same make up one area to the southeast away. I have a save of both of the corps coexisting. I note all the units in the Coalition corps show "[capt]" after them. I believe this is in the event code for the scenario.
