I am still seeing the bug where upgraded designs result in new + all old versions being displayed. There is no way to delete these old designs in game. If you build the newest version of the upgraded ship, it still builds the oldest version.
There are bugs in the ship building screen where if you select an item then remove it, as soon as you select another item, the first item reappears on the ship. Also, the end of the ship item box contains "artifacts" that are not really on the ship. This occurs consistently.
I am still being annoyed by some planets maintaining a very low approval rate even if they are nearly the same (buildings, size, upgrades, population, etc) as another planet that maintains a much higher approval rate. This can be as much as 40% vs. 100% variance there. I have 2 approval buildings with several grades of improvments, and adding new doesn't help. Even trade goods and super and galatic achv don't help much more than a very small amount. Something that is supposed to add a 20% improvement is lucky to add 2%. After a few turns, it drops back to where it was before. This is a very irritating thing.
