I keep getting icons appearing in the compass UI for Fabled or traders that, when you approach, are not there. Checked against the map they do not show there. It is frustrating with so many new things on the map so you do not always think to check against it with the compass to see which are the illusions and which are real. You can run for ages away from a real thing to find it was the illusion when they both show on the compass together. This is a bug that was present before latest offline mode update.
