Quick question regarding religion... I finished a game last night as the Ottomans (hadn't touched them since Vanilla, pleasantly surprised!). I managed to quickly spread my religion across the whole continent, bar a couple of Austrian cities on the other side which soon went down to the Germans. After unifying/pacifying said continent, leaving germany a crappy little city in the tundra and liberating a small Austrian city (Graz) for research agreement purposes, i sent an inquisitor to Vienna to get rid of the last remnant of Austria's religion. At that point, every single city on my continent followed my religion, even Austria's small resurected city. 2 dozen or so turns later, i see a austria great prophet make his way back to (my) Viena to convert it back... Question is. How did Austria manage to do that if every single city, including Graz, followed my religion?
