Wanted to ask about this. Playing ver 89. So far no bugs. Playing as Huns. Did not found a religion, but I have captured a Shinto holly city and it became my religion. Some time later I capture Mecca holly city of Islam, and now Islam becomes my first religion. Which I certainly don't want after spending all the effort of spreading Shinto and combating Islam. So I reloaded and did not capture Mecca this time. But now Arabia is again spamming me with their missionaries. Turning my cities all over again. Is there any way to capture Mecca, but not getting the Islam religion? Thank you.
