The neutrality learning centers produce 22 research and cost 4 maintenance, discovery spheres (the normally highest level research structure) produce 18 research and cost 4 maintenance... There is absolutely no reason why they should NOT replace them and autoupgrade on all planets (not to mention its annoying having them both on the list)
Also secret police only gives a +20% to morale (and is a superstructure)... this is a fraction of a regular moral boosting structure (ex, VR centers give +60%)
It will be great if there was something you could click to be taken to the next planet with an empty tile.
And choosing neutrality automatically gives you the equivalent of orbital terraformers, except its far FAR cheaper to research and construct. Do you even have to research the entire terraforming tree? why not just go straight with neutrality.
Clicking on "reset" when selecting traits for the terrans in the official campaign refunds you with the full 10 points, but leaves you with several bonuses (selecting a new bonus and then deselecting it overwrites it and properly resets the selection).
