So my character married Lord Andre from Sarleon, and after forming my own kingdom and while in the process of getting more lords I realized the fief I had assigned to him was currently unassigned, I then checked the faction entry in the game and he was not in my kingdom anymore, he went back to Sarleon. Fortunately I went to talk with him again and ordered him again to join my kingdom successfully but I wonder if he is going to leave again soon without any kind of warning, his relations with me are pretty high 80+. So is this some kind of bug or is there some game mechanic I'm not aware of? Perhaps he ran into Ulric in the field and he asked him to go back to Sarleon? Any ideas?
