Spirituality low

Hi, why does my spirituality rating drop to around 76% in the late game? I’m in year 99, population 1100+, plenty of food, desirability 100%, upgraded temple with 3 priests and 3 relics, upgraded shrines in proximity to all dwellings… 76% is remarkably low. What’s the trick to get spirituality high again? Do I need to place shrines near all Temporary Shelters that I’ve placed close to remote work camps and mines? What about remote hunter cabins and forager / fishing shacks? Are they deprived of sufficient spirituality without nearby shrines? Good tips would be appreciated :slight_smile:
