Sounds like you and Savoy have a different dynasty.So I've watched PU YouTube video and I'm still confused. I (Burgundy) am at peace, Savoy is at peace, Savoy has lower prestige than me, I'm the only Royal Marriage they have. This has been the case from 1498-1500 (so through two "phases" [if that's real]), yet I'm still getting "Nobe from House du Bourgogne succeeds to the throne" instead of PU. What else have I not checked?
