Since Yor planets are pretty much always at 100 percent approval, I wasn't sure if they can be culture flipped. The Yor just colonized a planet I want in a game I am playing. I have a constructor near by the planet, and was wondering if it is worth while to try and build the influence starbase. Or would this be a waste of time because Yor planets are immune to culture flipping? The Yor just colonized the planet so my influence star base would be up before the planet has much time to develop. Thanks for the advice!
