Xur is on the moon. Your probably wondering if this is credible information😉. It is. I haven’t “restarted” the shadow keep campaign, which I need to to to be able to go on to the moon(because of beyond light). I was checking the vendors of my characters and my warlock and hunter have been to the moon. Not my Titian because during this expansion I didn’t plan on using my Titian. Xur was not listed on my Titans’ list of vendors Because I haven’t“opened” the moon yet on that character. Good luck. 👍 Update. Turns out he was on the moon. May have been a coverup of a glitch or bug.
