When using "Zone Path" to find my way across multiple zones, the text will sometimes say "A mystical path appears before you" even though the path does not actually appear.
Absolutely warrants analysis. Don't forget, when you druid port to Tox forest and make a path to Marcia Amilgald(sp?), even though she's nearby, it suddenly can't help you and says it can't make a path.
This does happen from time to time. When it does, bring up the map and there is typically a red X where the path would have been drawn to. So even if you don't have the path, at least you can find out where you should go. One thing that I've seen cause this is when the path goes under the surface of the ground. If I'm standing on a hill or something, sometimes the path tries to go straight through the hill rather than along the surface.
I'm referencing this happens when she's actually there. When she's not there she doesn't show up in the Find window.
This has happened to me numerous times for a variety of reason over the years. Some of the reasons include paths to objects which need to be clicked to zone, NPCs which need to be spoken to in order to zone, 'unknown' routes, etc.
