Have you guys thought of making an event that allows a widow to inherit a title if her husband's line dies out? Like what happened with Lady Hornwood and (most likely) Lady Whent?
Spouses should be able to inherit titles yesch.
No, I mean they should be able to. Inheritance is hardcoded by the developers I think, but maybe an event could do it but I'm not sure.
What is the MB-GOTW mod? From what I can tell if someone has no heirs and no other dynasty members then a random courtier inherits.
When I have time I could try reverse-engineering the MB-GOTW files to do this, but it'll probably be a while before I get it working.
