In the picture there are two Research Centers under my Civilisation Capital on Earth. Each of the Research Centers is Level 3. How can this be? Each Research Center receives a level bonus from the adjacent Civ Capital and the other, adjacent Research Center. That is 2 levels bonus. So the Research Center should be Level 2, but here it is Level 3. Where comes the 3rd Level 1 bonus from? Or is this a bug?
