Here's a question:

Are you sure that it is *creating* those designs?
or might it just be that the "obsolete" tag isn't staying on?

I remember one game of stock SE4 which I took over for another player, where I couldn't obsolete a ship design. I could obsolete it, but it would be not obsolete on the next turn.

Also, have you tried playing the turn under Deluxe?
