Well I didn't need to. After restarting 4 times the flags just came back. I dont have an issue anymore I just figured the bug was worth reporting because it covered my screen with a baby face then replaced flags with baby's.
Summary: In the city of Argoron and its surrounding villages. The face of a baby appears suddenly instead of the northern empire flag. I checked to make sure it wasn't a lord who had broken away and somehow made it into their flag. this is not the case. it is still a part of the northern empire...
