Sorry about the wall of text... I have an ongoing problem with the "exploring the corridors of time" quest which is stopping me from continuing: I travel to Mercury and speak to Osiris, the quest is there to pick up (as an abandoned quest) so I collect it and the computer terminal thingy near him shows the blue quest marker above it - however, when I move towards it the notification disappears and I am unable to start the quest. If I go to orbit (or another location) the quest disappears from my quest page - I've watched it happen, it literally just vanishes from my quest page! If I subsequently go back to Osiris the quest is, yet again, ready to collect but the same thing happens every time. I've tried the following, all without success: Abandon the quest manually (before it disappears, obviously). Log in with a different character. Reboot everything. Log out of Playstation. Log out of Bungie D2 app. Do a sundial run. Visit every vendor to check for other outstanding quests. Visit Saint 14 (no other quests there either) I really don't know what else to try - any help would be gratefully received. If it matters I play on PS4 and my gamertag is "BigBadJuss", thanks
