It is frustrating to see. You know... this is not the only time I've seen bots or cheaters.

For instance, I saw a number of players in pixel perfect spots doing their... MSQ? They were in the Adder's Nest. IIRC, I saw a dozen of level ups in one second. I also saw some new players literally teleporting around the map, and even shooting at enemies from underground with their Archer, as if they have noclip. This was in Lower La Noscea back when I was just grinding a new class.

Perhaps this one is but another case of the bots at work...
