[Q]

I have reported earlier that stellar manipulation is researched very early and to high levels. It might have been a consequence of the ancient racial trait: if the AI sees no more warp points to unknown systems, he believes he is disconnected and researches stellar manipulation with highest priority. It might also be a problem in later games using the AI team mode when all systems are seen by all AI players. I don't know, if you have a script call like "all systems seen" that would prevent this.
