Hello I have managed to find myself with some occupied cities that were vassals of the main empire I was fighting at the end of the war we agreed terms but these cities were not part of them as they were owned by the vassal.  I think because the vassal split from their leige during the war I was at peace with them and I can neither give these cities back by liberating as they are occupied or anything... very confused with what to do now.  Has anyone else found themselves in this situation?
