I spend a lot...maybe too much time in the ship designer. I've noticed that after loading a game and resuming play, the designer parts don't have the colors they should have for windows, lighting, etc. For example, the Yor have mainly green lights, like in this ugly ship I threw together to test this bug:
Everything looks good. Lights are green and yellow. Then I save, exit, restart the game, and load the save. I start designing, but the new parts don't look right:
The lights for the new parts are gray, white, and boring. It makes me sad.
