Kongo cannot build Holy Sites. What is more, is that if you play as Kongo (as I did) and you conquer a Holy Site, it is destroyed. However, you still end up with some sort of "phantom holy site." In one game, I conquered an early Holy Site and even though it was destroyed, it kept generating Great Prophet points for me (but the interface wouldn't let me recruit the Great Prophet, even if I had reached the amount needed). Later on, once the AI's started building temples, I found that if I conquered a city with a Holy Site with a temple, the holy site would be destroyed but I would still gain the temple slot to hold relics. It would appear under the Great Works screen, though if you generated Tourism, it wouldn't appear on a particular spot under the Tourism lens. I did find this useful to get additional Relic slots as Kongo, but I strongly suspect this is a bug. Another issue is that AI's pantheon selection choice for Kongo. In my current game, they chose Sacred Path. That partly makes sense since there is jungle near their capital, but the AI should specifically NOT choose any pantheon beliefs which are reliant on Holy Sites, which Kongo cannot have. That includes: Dance of the Aurora Desert Folklore Sacred Path River Goddess God of Healing God of War AI Kongo should NEVER choose any of these pantheon beliefs (unless there are no other options).
