Feel free to create your own versions, cuz funny, editing ED445 into a Redguard is going to be a nightmare cuz I'll just HAVE to keep his MASS.
For some context, im a King of Norway, previous generation i conquered Sweden and gave the title, and independence, to my Son, and it went smoothly
Next generation, i decided to do the same with Denmark, i conquered it, solved Bordergore, gave Duchy of Sjaeland (or whatever) to my Son with intent to guve him kingdom title as soon as i could afford to usurp previous danish king (he annoying kept title without any de-jure counties and then went into a war)
but then I died of old age, my new King almost immediately had war declared on him by all his norwegian vassals and i had to fight it for a while, then help Swedish cousin fight off his tyranny war
In the meantime my brother who was meant to be king of sweden got mauled by a bear and died, leaving his 1 year old daughter in place
Once all that was over and I re-made the Denmark Kingdom title (it dissolved) I went to give my niece the Kingdom Title (im her warden and ally) but when i did one of her vassals stayed with me, i reloaded a save and googled it
"No counties outside de jure" saod google so i retracted his 2 vassals in poland and gave them independence
I have no double, triple and quadruple checked that he has no vassals or titles outside denmark, or even his duchy, but he still remains my vassal, wtf am i supposed to do?
