does de_desert_atrocity_v3 exist

[Blackmage]

So, I've realized. I've never seen the map "de_desert_atrocity_v3" played. In fact, it's not listed in the listmaps. The only place I've seen it listed is the admin map change menu, and always with the (!) after it. Is this map an easter egg, a mistake, or what?

No idea. Still has the (!) in map chooser, still not able to nominate, and never been played according to psychostats. Guess it's just an unfortunate anomaly.
