The camp for Wand of Imperceptibility including Koxiux the Imperceptible is not spawning 3 of the 5 mobs in the zone. not sure if it needs reset but the characters involved in camping the content are Skraal, Lillyrose, and Jiato. All of these characters are camping here in group for Wand of Imperceptability.
Someone pulls a mob in large numbers and the upset mob gets caught all over the erea. I think this server downtime has resolved the problem, but if someone pulls a large number of them, it will happen again.
