"Civilized" Hidden Agenda Bugged

[Zaarin]

I've suspected this before, but it became particularly apparent in my last game that the Civilized hidden agenda (likes civs who destroy barbarians; dislikes civs who do not) is bugged. Gilgamesh spawned with this agenda, and he harassed me the entire game about not clearing barbarians--the thing is, I was playing on a small map and literally every inch of it was covered in cities before the Medieval era. There was no place for barbarians to spawn. Even before that was the case, I was vigilant about barbarian busting. There must be some bug in how the game processes this agenda.
