The Company You Keep (Twin Adder) Aggressive Gnats on quest NPC

On top of the duty finder server issues there is an additional problem when doing this particular quest. The NPC for it is surrounded by aggressive gnats. During the extended wait time to get into the instance, these gnats attack the player. If the player is left alone the worst that happens is a timeout and an error and you can try again. If you're attacked, which happens a lot if no one is pulling the gnats away, you get stuck on the black loading screen and are forced to log in and out to fix it. This is a similar issue to the one that plagued the level 5 ARC quest with the box and monsters interrupting the CS.
