I'm playing as King of Leon. The king died during an active phase of conquest into southern Iberia. For some reason, some of the Sunni nobility are staying on. I'm not sure why. I have 4 Sunni vassals. Now that the king is dead and the heir is a 3 year old minor one of the Sunni nobles is my regent. This makes no sense to me. Why on Earth (esp in a game called Crusader Kings) would any Christian nation allow a Muslim to be the regent and Chancellor for their kingdom? I also can't change the regent. Is this a bug?
