In my game as the Habsburgs, I noticed that the Etichonen duke of Alsace had agnatic primogeniture succession and no living male relatives of his dynasty, meaning his throne would have to pass to a distant cousin: a Habsburg. How distant? 5th or 6th cousin distant. Then I thought of HTTT and its introduction of heirs with weak claims to the throne, and I think this would qualify as one of those instances. So why is there nothing to represent this? In such a circumstance, where a throne that is supposed to pass to an immediate relative passes instead to a family member so distant it's currently legal to marry him in certain countries, the recently deceased has a vassal who is his nephew or something. Shouldn't the nephew be able to contest the inheritance with more than just a weak claim? Moreover, I think the new ruler should have a penalty to vassal relations to reflect the disrespect incurred by (effectively) Leader Dies Heirless (Empires of the Middle Ages FTW!), so those same vassals might say the nephew has a stronger claim than the distant cousin and the law is unjust. As it is now, all heirs have "strong" claims to the throne.
Totally unrelated: in that same game, Scotland conquered England and formed Britannia.
