last game I just finished Pacal was running away tech wise and even killing everyone other than him and his vassal (Sitting Bull) wasn't enough for the diplo votes or domination. So, I decided to just try attacking Sitting Bull and capture his cities for votes. Interestingly, despite being a vassal of Pacal, Pacal didn't start attacking me (or any of my 4 vassals). He just pillaged some improvements at sea and used his bombers on some of my cities.
Is this normal behavior? Is this a cheesy exploit of sorts?
