This occurred in my last save file, I finished the haunted save, and deleted it. I have since had another save, and it was less eventful.
Chapter 1; The Duna Mission
I sent a manned crew to Duna’s surface, with plans to make the site a refueling station and surface base to launch rovers from. I launched them and I did all the things right, the crew were safe. I returned three years later, not touching the station dubbed Lufthansa Station. What I had found was beyond me.
