Before I started my science capital on a planet, I captured a small near worthless planet with one already built and then couldn't build on the planet I originally intended to. I had to destroy the whole colony before I could finally build it on my intended planet. Also, as one "acquires" planets, it would be nice to move the science/manufacturing/economic capitals to better locations where they would do more good, but you can't w/o wiping out the colony first (which is unrealistic to do in a tight game). Any chance of changing this?
