Summary​

AI forming cadet branch ignored matrilineal marriage

Description​

Both of my characters parents were of the same dynasty. The mother's side was my player line of characters through which I was trying to maintain the founding house of the dynasty, to keep this I married matrilineally even though at the time both parents were the same house. I am playing as the vassal king to my emperor grandfather (on father's side). This grandfather formed a new cadet branch resulting in the house of my character changing ignoring the fact that according to the marriage type of my parents I should remain in the original founding house (which the mother still remains in).

I suspect the issue is that when determining which characters house to change at the formation of a cadet branch it looks for descendants of the character forming the cadet branch that are of the same house (dynasty?) without checking which parent house is inherited from, creating this weird edge case when both parents are of the same house before the formation of the cadet branch but not after.

Steps to reproduce​

Form a cadet branch using a character with grandchildren through a son matrilineally married to a member of the same house who would not become a member of your new house.

expected: The grandchildren should remain in the original house as they inherit through the mother
actual: The grandchildren change to become members of your new cadet branch
