I really need help. When I look on the tech tree and see a new ship design in one of the techs it says other techs required and lists the techs. So I research the other techs but I still don't get the new ship design in the starport build menu. Normally I'd think Im just doing something wrong but I got it to work for the Star Fury fighter and nothing else. Anyone know what's going on? Is this some kind of glitch or am I just not doing something?
