I had a little snoot around to see if I could find any other solutions. Apparently leaving the system usually fixes it, but as in your case, not always. But apparently, any depot will do. So if you see another one, destroy it and see if it fixes it. You can hunt them out by scanning for secure frequencies or using your exocraft scanner. I'm gonna have to do a lot of troubleshooting before I can continue with my Expedition Mode save. I think it's the latest Nvidia drivers, but every time a Freighter, including my own, loads in. The gfx drivers crash and I have to restart the game. Just a little bit irritating when I'm trying to do the last 2 Frigate missions for an expedition patch! Seems to be happening to a lot of people in various games though, so I'm going to try a roll-back and clean install. See if I can get it functional again.
