I was hoping that this would get addressed in 1.1 even though I never saw it fixed in the betas... But Unlike virtually every other form of building upgrade, Neutrality Learning Centers DO NOT automatically queue up to be upgraded after you research them. This means that you get to go through the tediously long process of manually upgrading all your research centers, If you've got an empire with 88 Colonies like the game I'm currently playing this can literally take 30 minutes or more. Hopefully this will be addressed soon.
