I have some questions around vassal inheritance, specifically how to stop it. I am the King of Italy and have gained independance from the HRE (feel I might have done it too soon, as previously I only had to fight other vassals to reclaim dejure provinces, even with HRE medium crown authority which I though prevented that, but now I have to fight the whole empire).
Seemingly every 5-10 years I lose a random province to the HRE, and have about 6 counties and dukes in the vassal inheritance wanring icon. It's kinda cool cause I have gained a bunch of German provinces too, but they aren't a whole lot of use to me as their dotted all over the place, and I perfer tidy borders. I am pretty sure I understand how and why it's happening, usually looks like stupid AI matrilineal marrigaes where the son has a different leige, but sometimes when I go into the dynastly and check both the owners, and their heirs I am the leige, even if once removed by a duke.
I have finally managed to pass high crown authority but the existing inheritance warnings are still there, I am guessing because they were done before I passed high crown authority. The only way I can think to stop these is either revoke the title (annoying because they are mostly at 100 relations, and there are heaps), kill them all which isn't practical because it's too expensive and I don't think I have ever had more than a 30 percent success chance with assinations, and plots which I have yet to see a valid one (seems like I can always kill everyone except the person I want to with these).
The only reason this really annoys me is that for some stupid reason you can only claim one county per war, even if you have 5 or so dejure claims (you really should be able to press all similar claims like you can if you've managed to fibricate claims on two provinces in the same kingdom, just make the warscore higher or harder to achieve). Just means instead of expanding I am just fighting to get my stuff back.
One other quick question, what is the deal with abdicating the throne, it says it will go to my heir but it always goes to some random person further down the line, and I noice it says 4 different people will recieve an event, is this like a vote or something?
ps. I only played one short game of the vanilla CK2, I use that prince and thane mode and I can't remember which stuff is orignal, or modded.
