Then it must be me. Well I guess this could be put down as one of the crazy things to do. Conquer the Provinces around the Pope. Build like crazy. Smack the Pope around through a couple of emergences, then when he comes back with one honking huge army, emigrate to a nice safe local, like N. Africa. Then stay out of his way for a while while you build up your new local.

The Pope will start conquering everything, and building like crazy. He can turn into a huge behemoth if left unchecked. And fighting him in a prolonged battle is a pain in the hoop. Instant excomm, grumpy generals, and I suppose if you set him up right in the beginning one effective army.

If no one else has encountered it it might be fun for you. As for me I guess I'm going to have to change tactics.
