Okay, something really strange has been going on with my succession to the Roman Empire.
So, I set up the Roman Empire. I have two sons. Both born in the purple, not bastards, everything's normal with them, agnatic-cogntic primogeniture. Naturally my older son is going to inherit everything.
When I set up the Roman Empire, my older son becomes the heir to the Roman Empire, but my younger son all of a sudden becomes heir to everything else - my kingdom, duchies, counties, etc. Why?
Well, I'm not sure what's going on, so I just kill the younger son and my older son inherits. But then another odd thing happens.
I marry, my wife produces 4 daughters. I divorce my wife and remarry, she produces a daughter. The 5th daughter all of a sudden becomes the heir to the Roman Empire and all of my duchies, but my oldest daughter remains the heir to the Kingdom of Bulgaria.
So, can anyone explain what's going on here?
