AI making stupid marriage decisions?

[Ruisuki]

I managed to get the emperor of france to matrilineally marry my sister after some assassinations. They have 4 kids together of my dynasty yet after his betrothal to one of my landed dynasty members ended in failure because of her death the emperor now matri married my nephew to a countess with 56 dynasty prestige. What is this? Shes not even of his dynasty, why be this stupid? Is it a bug?

This is pretty standard. Matrimarry heirs, not rulers, raise their kids in your court and arrange their marriages yourself.

yeah. sometimes they inherit before popping kids. its been 9 years with another couple for example, and still no baby.
