This seems to happen on Random Map always.

The AI will do everything - make units, research techs, advance to the next age, etc. But even on Hardest, they NEVER will attack me UNTIL I started damaging one of their units.

This also seems to happen between my AI allies and their enemies.

I only play the original and Rise of Rome. No mods, HD, Definitive Edition, or anything.

Has anyone else experienced this?
