navigation arrow vanished mid use and can't get it back

[sgtwtf]

so i was traveling and the arrow just poofed away. I have disabled all add-ons, removed and re-added the arrow in the config, tried a different profile, logged out and renamed the zygor folders in the add-on and appdata and reloaded the ui and no change. i did see once after a relaunch of wow, for a fraction of a second what looked like a grid of white dots about where the arrow should be.

Have you tried changing steps? Not ever step will have an arrow showing.

i'm having the same issue with my Navigation/WP Arrow.

my Zygor starts off with no Navigation Arrow and then when i re-enable it, it shows "travel system initializing" and disappears.

I've deleted the zygor files and saved vars from before and reinstalled. I've also tried repairing in the app. Please help.

EDIT: i've also tested with all other Addons off.

EDIT 2: I disabled the addon 'World Quest Tracker' and it fixed the issue. hope this helps others.
