Steve -
Two things, both related to ground bases. First, is there a way to upgrade them? If not, there really needs to be a way to do that. I know this has been brought up before, but I think the only reason it hasn't been a bigger issue is because Aurora keeps changing so much that no one has had a particularly long campaign yet. I know I can't resist upgrading to the latest version.
Second, in the Twin Moons campaign a ground base on one of the home planets was destroyed in the Five Minute War, and it left wreckage that is now hanging in space, stationary in the orbit of the main planet. I think that ground bases probably shouldn't leave wreckage, or that they should remain on the planet where the base was located.
