Anyone know why you cannot Crusade as the Pope in XL? I tried a His Highness campaign yesterday for the first time, and His GA goals are to crusade, but I couldn't build a Chapter House anywhere. And yeah, I had all of the prerequisite buildings. It was shaping up to be fun, but alas I couldn't fulfill my goals so I stopped.

Also, does anyone get excommed when you play as the Pope? I was never at war with Catholic countries, so I didn't find out.
