I didn’t catch this right away, but load the save and check my tech, emp defenses and Imperial Academy show that I acquired them by other means, except I didn’t, or shouldn’t have. I cleared a monster at Dant and one of the planets there has ancient artifacts, I believe that’s how I got these techs even though I haven’t colonized it yet. I only noticed because I went to design new ships and saw tech I knew I had not researched. Perhaps you can check if the techs are being given to the first to visit rather than colonize. P.S. As long as I exit to desktop before starting a new game, I am seeing much better performance across the board. Edit The second tech is Imperial Academy, not gravitational scanner as originally written. Also, upon colonizing the planet, I received two more techs
