When I want to create a new ship design I either create a new one entirely from scratch or use a template. I then proceed to place weapons, engines, and defenses on the ship. After giving it a name and clicking save I get a message stating that I cannot edit the core ship design. I do not know what I am doing wrong and why this message pops up. It is very annoying because I cannot create any new ship designs in the game. How can I fix this? Or is it just me being dumb and somehow I am editing the core ship design? Thanks for the help!
