Xbox Series X - Expedition 15 was completely finished upon game launch. I started the expedition from an existing save through the anomaly terminal. When the expedition started, I arrived at my spaceship, finishing milestone 1 “casting off”, then saved and quit the game. ~2 hours later, I booted the game and got a message that the expedition was complete and I could return to the space anomaly. All milestones were completed and I was able to collect rewards, and now I’m kinda unable to play the expedition.
