Please explain the issue you experienced in the most condensed way possible
My character's son and heir is married patrilineally to a member of the same dynasty. Her father (my character's brother) has just established a cadet branch, which took his children obviously, BUT it ALSO took grandchildren of the dynasty in a Patrilineal marriage

Please explain how to reproduce the issue
Have a marriage with children within your own dynasty prior to cadet branch formation, form a cadet branch with the father of the mother/maternal grandfather of the children, the children will end up in the cadet branch EVEN THOUGH the marriage is patrilineal

Is there anything else you think could help us identify/replicate the issue?
Savefile attatched shows how it happened to me in a multiplayer game I was doing with friends, I am the only one playing in my dynasty and a landed family member controlled by an AI is the one that decided to form a cadet branch

I have attached a save game
Yes
