I boarded and took a ship during a quest and flew to New Atlantis. I saved the game and stopped playing for the night only to find the ship left me when I loaded up that save the next day.
I laughed at first, but then I realized I'd have found Starfield vastly more interesting if weird stuff like this happened all the time on purpose and they leaned into it with small quests. This one bug delighted me more than any of the actual quests I can remember at this point.
It almost feels like Starfield was ambitious in the wrong ways. Bethesda trying to aim for Disco Elysium-ish oddness might not have turned out great, but I think it would have made more of a lasting impression.
