An new version for patch 1.04 released! It implements the map fix (thanks a bunch Zaldax), AND I have a file that flips Muslims/Pagans to playable. I want this mod to be compatible with others that mess with religions.txt, so it's a separate download. I haven't put the Kingdom of Brythonia in, and I won't unless people ask me to release a separate landed_titles.txt that has it. I might wind up making duchies of Morgannwg and Powys, and give Wales some special hoops to form... possibly create a Kingdom of Brittany, too.
There's also a new CB to simulate the Almohad sack of Ghana! It might not exactly be balanced, and I'm definitely going to need to buff Mauretania before I have them starting out trying to smash Ghana. Removing the warrior cult from west africa cultures probably helped.
