Louna is supposed to be at her raft, which gets players to Whalefall in Amenos. This raft is right on the edge of the beach and the Compass shows her location as being very near the raft, but she is no where to be found. After speaking to Leander, he tells me to find her. To get to the west beach from Leander, you go through a cave-like tunnel right where he is standing and end up on the beach just a short distance from the raft. Have looked for this NPC everywhere. She is not the tunnel, anywhere near her raft, or anywhere along the beach.

Screenshot of the raft from a distance, with mini-map location. Compass does show an icon for her, but the screenshot does not show that.
