Rajah of Minyue and Langkasuka
I've had this result as well. I think it is bugged.
Is Tomyris' Agenda Approval animation bugged as well? I've become her friend several times, and that animation has never shown up.
I've never seen either of Philip II's Agenda animations as well. Must be because he usually fails to found his own religion in my games, and even when he does, he fails to spread to it to my cities. I need to try converting his cities to see if his Agenda Disapproval works....
