Ship design is buggy, as many have pointed out. One thing I didn't notice is the quick build list from a planet. Every name I have ever given to a ship, whether I ever built it or not, and whether I've deleted it or clicked obsolete shows up here. So I have gun ship, gun ship, gun ship, gun ship1, gunship 2, etc... you get the picture.... very annoying.

The other problem, is probably related. The stardock menu does not correctly indicate the number of which ship you've built. this is probably related to the game not properly deleting the names of similar but older ships which are now obsolete. So I had a bunch of gun ships, now they're updated to gunship 1, now I'm trying to update gunship 1 and I have 10 of them but it says 0. This only happens occasionally by the way.

Oh yes, not sure if this is a bug, but I had about 2000 bucks, and I pressed next turn a few times, and I look down and I have 100! I didn't buy anything. No idea what happened.
