Directional arrow spins and says "Enter termite cave. Go to - "

Dominion: Deradune - Step 119, "Mitey Infestation"

After leaving Exo-Lab79 you are directed to enter the termite cave however the directional arrow just spins and does not point to the termite cave. The termite cave can be found by clicking on the quest and the WS default arrow will point the way.

Hope this helps

It might just not be seeing the map change properly after exiting the Exo-Lab. Try just moving back and forward a step after you exit the lab to see if that gets it to point in the right direction.
