Hi, I'm playing on Xbox and I have the same issue I see other people have - I'm stuck on the mission Saving Caius Thorn, and can't seem to progress.

Would be grateful if someone could "progress" my account as I see from the fixes on other people's posts.

If it helps, I played a bit in single player, then played coop with a friend for a while.  Then came back to my own game and found the issue of not being able to progress.

Thanks in advance :)
