By "Religions disabled" I mean religions were not being founded when a trigger tech was discovered. I played a game into the middle ages thinking they were simply being founded on another continent faster than me but even after contact the entire world lacked faith. No permutation of Choose or Limited religions mattered. My default playstyle is to leave them off. Didn't fiddle with inquisitions. But I think you're right that it was a cache issue. I started up a ton of Blitz games as Indians so I could rush Hinduism to test different settings. After I tried toggling "Multiple Religions" in BUG they seem to be founding again, even when I set it back on a new game.
