On my PS5 and was on my Warlock headed to the Gilded Precept Legend Lost sector, when it disappeared from my map and launch flag also no longer there when I arrived. I went to orbit and still gone. Changed characters to both Titan and Hunter and it’s still there for both of those characters and I can both travel and launch the GP Legend LS for both of those characters. I logged out from the game, closed D2, relaunched the game and still missing - only from Warlock. And yes I have completed all Neomuna lost sectors on all characters - it was ON the map and I was on Neomuna when it disappeared. I then logged out, shut down my PS5 and unplugged for about 20 minutes. Just finished logging back in. Still missing ONLY from Warlock.
