I'm playing a custom game of Civilization 6 with no barbarians. My opponent, Gilgamesh, just sent me the following complaint:
How can you let those Barbarians run amok so close to your home?
(You have transgressed Gilgamesh's agenda, Civilized)
This is a barbarian-free game. What in the world is he complaining about?
I'm playing with no mods. I have the following DLC: Khmer & Indonesia; Nubia; Persia & Macedon; Australia; Poland; Vikings.
