I have a related quibble. It isn't so much that I don't want to keep my designs ( I do for future games) but once I've obsoleted the design in my current game, I don't want to have to do it again every time I load a game. I typically only get to play 1-2 hours a few time per week and it's really annoying to have to obsolete all my old designs every time I start to play. I typically play huge galaxies with ~40-50 opponents so by late game I have a lot of designs obsoleted.
Is it possible to keep the obsolete flag something that saves to avoid this please?
