[PvK]

Well, one thing to do would be to specify one of the three generic AI's: Neutral, Defensive, or Aggressive, instead of the shipset based one, for your empire file. This is set during empire creation.

The other thing to do is in each PBW game, to go and specify that the "AI should not make any changes to the empire" when you miss a turn. This is under Empire / Settings during play.
