I'm completely unable to interact with the final chest for the exotic khvostov, and an interact prompt of any kinda doesn't even show. I have the exotic mote and have placed all of the traveller statues, I've tried moving the mote to my vault and back, leaving the instance and relaunching and jumping off the side and respawning with no effect. Only thing I can think of that I haven't done is try on another character, but my other characters aren't far enough through the campaign to access it yet. My guess as to why this happened is that my friend who I was doing the quest with at the time spawned the chest while I was in another area, and then I placed the statues while that chest was still present. They were also only able to open the chest after I had left the fireteam. Proof of having both the chest and mote: https://imgur.com/a/RmYc3ZB Edit: Problem is fixed
