I was able to go into Echo: Faultline through Ouroboros and get Newsgirl where it was supposed to be. I also found Apex near where Faultless Mystic is in the main timeline. Not sure where to find the old Faultless Mystic, though.
Apex: 281 yards SW of Ouro portal, on top of a parking structure (278.5, 57.1, -2257.0)
Newsman/Newsgirl: 513 yards S of Dark Canyons marker (1125.2, -26.9, 1296.1)
If anyone can help find Faultless Mystic, though, that would be fantastic.
