Hi there!
There is a continuity error (or bug?) in the Dry Steppes Jakha Basin area:
After Zolaya and Oyuun are reunited and ride off (Whispers from the Past stage “Speak to Lorath at the entrance of the Offal Pits”), Zolaya can still be found standing next to Lorath in the Hidden Overlook camp, while both of them should be gone.
