During my current game, Hannibal, Monarch, I have built some of the religious wonders and have noticed some don't follow the religion of the owner when you change religions. I have built Sistine, Apostolic, and Spiral Minaret, missed Sankore. I changed religions after I built Sistine and Apostolic and noticed that Apostolic didn't follow my religion while Sistine did. Built Spiral after I swapped. Do Spiral and Sankore follow the religion of the owner or do they stay the religion they were built under?
