Hi all. This bug has been going on for some time but I never got around to making a post. Every time I go to Xur on my main, he does not offer the exotic cipher quest "Xenology". I think I abandoned it several months ago when I first started playing again, not realizing my mistake. The quest doesn't show up in the quest archive, my quests tab, nor in his inventory. My two other characters have the quest in their quest tabs and shows "6 of 21" for its progression. So far the forums haven't yielded any helpful tips and I don't know what to do. I can try to complete it on the other characters although it will take some time due to being a college student. Any tips or ideas would be greatly appreciated!
