I usually don't care about culture conversion at all, but being the Mongol Empire, you obviously want to have a lot of Mongol provinces to raise as many Banners as possible. I did not know it was possible to culture convert provinces that have a "wrong" religion, even the wiki says they need to be True Faith of the owner to be able to culture-convert them. When did they change this, was it mentioned in any change-log, or is this something Mongol-specific???
