I can't promote the noble I want to Duke of Gaston. For some weird reason my only option is a current knight of Gaston. Is that some other new rule I wasn't aware of? Did I have to start by having that lord step down, then become a knight of Gaston, then I would be able to step down from Gaston make him lord of it?
See what I'm getting at with this being more difficult then it should be?
Why not just an option "Announce your region as a new duchy" which automatically makes you duke of THAT duchy regardless of whether you were a duke of another duchy or not?
