So this seems to -only- happen when I'm playing with CK2+, but the pope seems to be a drooling moron and gives away the Papacy to the Grandmaster of the Papal Knights, causing it to be destroyed. I use a mod that is designed to fix border gore, and I use that to give it back to him. Three days later, he gives it away. Again. He has no other duchy, and yet he insists on giving it to the Papal Knights. How do i make him stop?
