I suppose you could try to assign someone else as Marshal and then reassigning yourself. Also I imagine that there could be a flag in the player's party records that is stuck indicating that you are captured but that'd take a little research that I won't be able to do till the end of the day. Could also try getting it changed by getting yourself captured by a regular army in a battle.

Do you have any save game editors open? If the savegame is loaded into MnBSaveGameEditor v1_03, for example, the game will fail to save with an error.
