I was King of Eire, and I've created the Empire of Alba.
I was surprised to notice that the Kingdom of Eire and the Empire of Alba have two separate successors.
What happens when I die, if two different kinsman get voted? I guess I would have the Empire, but can I have an Empire without having a Kingdom, and having a Duchy (Mide) inside that Kingdom itself?
(sure, I could just destroy the kingdoms, but that's beside the point of this question)
I also have the Kingdom of Wales, I've not created the Kingdom of Alba/Scotland, and while I control most of England and I'm sometimes voted to be heir of England, it's still independent.
