I took over the Free Folk and the Night's Watch factions, therefore I managed to create my own one and I named it ''House of the Flaming Heart'' since I'm role playing as a character that came from Dragonstone.
The bug happened when I went inside the Eastwatch Harbour. (https://imgur.com/3t3uhvU).
A window popped out of me talking to myself ( https://imgur.com/b8fthC6 ) out of pure curiosity and stupidity I clicked on the ''I offer you my sword in vassalage''. After clicking on that the whole of my kingdom color changed from brown to blue, and the name changed from ''House of the Flaming Heart'' to ''Player's Faction''. ( https://imgur.com/7Kc8cQo ).
When I enter the towns/castles that I do not even own this message pops up ( https://imgur.com/jAu7YlH ).
But when I press on ''Character'' and go to the ''My Kingdom'' option ( https://imgur.com/dFErhfb ), it says that I am not a ruler of any factions.
So there is me right now literally mindfucked on what happened, so I wanted to ask if there is a chance to somehow roll back my save for a couple of days or somehow fix this bug. I've spent a lot of time and IG days to come this far, and I really don't want to lose it all by just one stupid mistake and bug that I triggered.
Thanks in advance.
