Similar question to Woopzilla above. (2.1.6 vanilla, btw)
Playing as Ireland+Wales, some time ago in my game, I pressed an unlanded kinsman's claim on Scotland while Scotland was at war with Norway for the King of Norway's personal claim on Scotland. Norway won (gaining 'Skottland' as the game now called it), but my war continued, now against Norway, which I won. Upon winning the war, the unlanded kinsman claimant became King of Scotland, but instead of getting the de jure capital county of Scotland (Dunbar?), he got the de jure capital county of Norway (Bergenshus) instead, leaving the King of Norway with only a Barony for directly-held land. (My kinsman promptly gave up the Kingdom to the former King of Scotland, likely due to a faction firing off.)
1) Was it WAD that my war for my kinsman's claim on Scotland continued even after Norway's war for Scotland had ended with Scotland becoming part of Norway? At the time I was surprised as I thought the war would end inconclusively due to the title changing ownership, so the landed ruler I was at war with no longer held the desired title.
2) Was it WAD that upon winning the war my kinsman gained Bergenshus instead of Dunbar?
