Yesterday i was questing in hrundle fjord when i noticed the coven frostbeaks all gathered in one specific area not moving what so ever, i thought it would fix it self but i was wrong. Today the same thing happened again its just a small bug and thought i should let people know.
Interestingly, I sent a bug report to support along with a screen shot of that very same problem a couple of weeks ago. Seems the bug has returned.
