So I was going to ask about why some counties just go independent, but I think I figured it out myself. It's the event where a host with some gold asks for a county in return for 150 gold, for some random vassal, and so they accept and for some reason this county then goes independent rather than staying a vassal of you? When I look at the history it's just a blank with no reason given for how they got the county.
Is it intended that they go independent? If so then why? I could understand if they go independent when the top liege gives them a county but not if some sub-count or duke gives it to them.
