Ship designs that I created in a previous game (under Beta 4 "first version") are now re-appearing in a new game after I create my first new ship design. The old game ships that are appearing have all the whitespace stripped out of their names. Example:

Used to have a ship (in old game) named: Observer MK II
In new game I see my old ship, now named: ObserverMKII

I remember something like this happening in Beta 3, and it turned out that the game was storing ship designs with the main game data files, rather than storing them with the Saved Game data (where they belong). If this is true, then you would not be able to take a Saved Game from one computer and play it on another computer.
