The best I can do, I'm afraid, is to refer you to the Stainless Steel forum at twcenter.net, it's in hosted mods for kingdoms. You'll probably have more luck there since many of the mod contributors frequent those forums.
As for a remedy, I guess the old reload a save from a few turns back and do something different may resolve the issue. Sounds like it has something to do with your king getting the ancillary Kingmaker, but that might be of little use...

Good luck!
