Ok. My guess is they bought a version of the game that you didn’t (in which theirs came with an emblem). My guess is you may need to see about getting back on their pc & seeing if you can download any emblem content (likely from a preorder or deluxe edition) to see if this resolves it.
Okay, so I played on a friends PC who has preordered Beyond Light, which I know gives an emblem. I, however, have not preordered Beyond Light yet. Does that emblem show up in the General tab? If so, that's probably the culprit.
So unfortunately, after preordering Beyond Light and acquiring the emblem, that did not fix the problem. He must have another emblem that I don't know about. Worth the try, though, and I was gonna preorder today anyways, haha! Thanks for the help, hopefully I can figure this out.
