So as we know the AI is getting worked on and needs some help. I believe however that the Mystics of Polapel have a "nation specific" bug. I have started 12 games now to test and all results are the same.
So Polapel doesnt expand at all. Every single game they have the same city without any pioneers or their sovereign exploring. For that matter their sovereign just stays in the same spot everygame (usually 1 spot to the left of the city).
Not a huge deal but a waste of an AI nation at this point.
