Just noticed some strange behavior. Somehow civics have been enacted in my game which I definitely did not select myself. And to enact them requires techs which I havent yet researched. And nobody else has researched these techs yet.
If I try to change my civic settings, these too advanced civics are - correctly - not selectable.
Looking at the tooltips, the same set of too advanced techs has also been enacted for all other civs in the game.
Here an example, all civs have the religious civic "Celebrity Worship" (alternatively called "Cult of Personality") enacted, which requires Flight (not yet researched by any civ, we are all in the Renaissance or Medieval eras). Interestingly, for William of the Netherlands, in the tooltip it is shown as enacted, but according to the overview, he still has got "Organised Faith". In the screen for my civilisation, overview and tooltip both show "Celebrity Worship"/"Cult of Personality", which is active, as I am able to build "Idols" in all my cities.

On the contrary, in this example, Kanxi of the Manchu has a more advanced economy civ shown in the overview than in the tooltip (nobody in the game has researched Corporations yet):

I don't have older savegames without all these civics selected, so I can't tell when this change did happen.
Perhaps it is connected with the begin of the Renaissance Era ? William of the Netherlands, in the example above, is one of the few civs who hasn't yet entered the Renaissance Era:

On the other hand, Kanxi of the Manchu is still in the Renaissance era, like me.
If Civic and Reform (v19) doesn't cause this, it must be the effect of another mod. I am playing with ca. 50 mods (ca. 20 of them additional civs).
But the only mods of which I think they could possibly create this effect, are the Enlightenment Era Mod (v8) and the Future Age Mod.
