Here are a few bugs I've noticed. Sorry if they're duplicates:

1] When attacking with 2 ships in a fleet versus a planet, upon winning my ship's HP actually went UP, not down.
2] When filling a planet's social build queue, after filling the last request, the cursor highlights the first thing in the queue, but when I hit "Purchase" it's something different.
3] When I'm in a planet screen and I go to the "Build Ship" window, hitting DONE puts me back to the space screen and the "Back to PLanet" button cancels my changes and puts me back to the planet. I want to commit my changes AND go back to the planet. Sometimes I'm just reorganizing, flipping through planets and tweaking things. If I change a starport option I have to start over again and it's annoying.
