I can't remember if you've seen this at all ... Two bugs maybe ...
(1) Default Race Weapons/Propulsion/Armor Loaded in Design ... when during customization, those are removed and replaced with something different.
(2) In Design screen, if you modify either a ship or starbase and then toggle to the other design type (ship/starbase), you will not get a message that your current changes will not be saved (i.e. the warning you get when selecting return).
