Playing as bulgarian king under byzantine empire, i still lack Duchy of Vidin. I saw Vidin title owned by couple of old guy without son, after they died their heir is someone at other court. I invite the heir to my court, marry him matrinileal and give him some city for land. After that i kill the owner of Vidin. But after they die, my vassal go to become the next Duchy of Vidin with my daughter as his Duchess, and they become the vassal of Byzantine Empire, not me. Is hoping to expand by vassal inheritance is not possible?
Anyone know what is the formula about what will you get when as a king you declared war against another kingdom for a vassal duchy title? I never get the complete duchy when i fight for my vassal claim. Usually i try to find claimant of one duchy, give him land, declare war. For example from 1 Duchy with 3 de jure counties, at best i only get 2, sometime none of the counties, but only the duchy title for my vassal.
