I hadn't noticed. The UP in its current state annoys me so much that I keep it off. I'll try to remember to turn it back on to check it out.

I have on many occasions, found that I have to go out of my to attack the AIs because their influence threatens my colonies. However, not long after, my recently conquered colonies are threatened by foreign influence, and taking them has done little to stop the influence that threatened my earlier colonies.
