I don't know exactly what happened but I had a game playing as Robb, managed to save and reload fine several times, but came back from a break to find that when I loaded I was playing as Balon Greyjoy instead. This was on the scenario map.
I know about loading the game from the mod menu and other blah blah stuff.
I will just start another game, but figured you should know.
Thanks for the AMAZING mod!
