Okay, that's odd. I haven't had a chance to test six-plus religions yet (still technically on hiatus, easing my way back a little by answering comments finally), but Chris Hatch did describe anything above five as a "private" religion or cult. Maybe it's working as intended.

When I have a chance to fire up my testerhood again, I'll let you know, but Larky literally didn't touch that functionality, and neither did I.
