Problem with extreme AI in skirmish

My extreme AI plays like the easiest AI, I am in the feudal age he’s still stuck in the dark age with like 3 vills

Hi! I’ve faced the same problem some time ago and found that there was an AI Mod that conflicted with the built in AI.

What I did is go to the Mods section and disable any unwanted mods, in particular those that had to do with AI packs or so.

Good luck!
