One thing I've noticed with the Mongol and Nahua cultures is that they are locked into realmwide Agnatic regardless of what religion they pick or convert to. I've also noticed that baronies underneath Republics are also locked into Agnatic regardless of religion. I was wondering what I'd need to change in the other cultures to make this a game wide thing as there is no option for realmwide Salic or Agnatic unless you play as a Muslim or Tengri.
