Seems like my save forgot which faction i joined, however, everything else is still fine.

If i try to talk with Galmar @ Falkenring (I dunno the translation, should be hawks ring) he doesn't know that I am a storm coat.
Additionally i sometimes get errors "Warning: GetMyHoldFactionControllerMarking() myHoldOwner property expected to be 1 or 2, instead have:0
My guess is that variable defines which faction i am.

Does anyone know the command to set that variable to 1 or 2? And which value is storm coat?

I also have this issue, and I've seen mention of it on several other boards. Have not seen any official responses other than "restart your game," not an attractive option after 100+ hours invested into one character...

Reload from a previous save.

And if that's not an option?

This is part of why one is supposed to keep multiple saves, and possibly backups, in games. It's like this for every game in existence.

I'll wait for someone to post a simple explanation how to change the value of this state variable.
