Forbidden Oasis Quest

every time you travel she'll move, its best to just home in on her once you get the marker, don't fast travel to get to her

She's always seems to be near the spider cave when I'm in the area, whether I'm looking for her or not.

I left the area and came back to the camp near the water and yhe quest marker is there but she is not. Should I just wander around the lagoon and Wait? I see that the quest marker moves from time to time, but when I get to hehe new location she is gone. This is Maddening!,

What I encountered in my PTs. She could be :

* spawned in the wall of a cave. However I could still talk to her as she's partially embedded in it.
* spawned inside the last chamber of the temple
* spawned at the side of a high ledge

The worst spawn of all is not she, but the guy at Hinterlands, where you get the horses. He gives the quest to build watchtowers. I picked it up from him and couldn't turn it in because he ended up under the map exit. I had to scrub that PT and restart all over again. That was the only one off for him. *cross fingers*
