Problem: Depending on what techs you research first, the automatic upgrade of research facilities is faulty in respect to Neutrality Learning Centers. The computer might choose to upgrade to invention matrices or Discovery Spheres, although Neutrality Learning Centers are available.
A huge annoyance on bigger maps since you have to do it all manually.
Fix: Have the computer check for highest value in buildings, this would make sure research facilities are automatically upgraded to NLCs, not other buildings.
