I was running the daily lost sector "Aphelion's Rest", I exited to adjust my loadout and when I tried to re-enter it is no longer there. There is no banner and also no map marker any longer. I asked the few guardians who were also running it in my instance and they also reported it to be missing. I have asked other's in the clan if they are able to see it and some are and some are not. I am not sure what the deal is but restarting Steam and Destiny 2 has not fixed it, It is completely missing now for some reason.
