I always like to start each new game from scratch and adapt my gameplay to suit events that occur. So is there any way of preventing ship designs from old games from reappearing in late games when I research the technologies for them?
This was especially annoying during one game where about 7 versions of a fighter that was ideal in a previous game, but was next to useless in my current game, kept turning up on my shipyard list.
I thought about deleting them from the data files, but this might make the older games unplayable (not sure).
Anything else that can be done?
