Hello, I'm playing a game as the Khmer Empire, who get +1 housing from a Holy Site on a river. On top of that, I chose the Pantheon bonus 'Rover Goddess' (picture 3) which adds another +2 housing under the same conditions. In picture 1, you can see that I have a Holy Site up and running, but am not receiving any housing from districts. It used to be 11 total (that's how I grew to 10 pop so quick), before my Holy Site was pillaged and repaired. In picture 2, you can see a city with a Holy Site that hasn't been pillaged. It is receiving the bonuses correctly.
