In the hidden arcana story quest when I get to the domain of light I fight the small crystal golems, get the red light on my character and go to the circle to get protective bond. I get protective bond and finish off the golems and go back to the circle to refresh my protective bond. At this point it always disconnects me from the server. Has happened twice now. My connection is fine and I can always log back in immediately but all progress on quest is of course nullified.
