So, the problem is basically this. I'm an Emperor of Byzantine with Absolute CA. I was sure that High and Absolute CA means I can't lose land through inheritance. But lo and behold, one of my dukes inherits united Kingdom of Poland and Hungary, automatically becoming independent and snatching two of my duchies with him. And yes, I've checked, both Poland and Hungary have low CA.
I'm pretty sure that was a way to abuse it before (making future king outside the realm your vassal count), but this fix of a problem isn't any better.
