"Duster" quest in Ak'anon

[fwaits]

Can anyone confirm if the Duster V mob is in game and this quest is completable? I've gotten the Duster X spawn and drop, but cannot find the Duster V mob after spending a decent amount of time looking. I even looked at quest info from a couple sites and he's supposed to be the easier of the 2 mobs to get. Anyway, if anyone can confirm that they have seen this mob and/or completed this quest let me know. Thanks!

I have done the quest - if it the one for the backpack.
