[WTF] Naxxramas near dalaran's crater

[Nyarly]

Hi, i'm playing on a french private server version 3.2.2a and some guys noticed that there were a necropolis near dalaran's crater partially coming out from the ground.
I went there with 5 guys from my guild to check if it was client-side but we all saw it.
Next i tryed to check on a local server (3.2.2a) if it was here too (to ensure it's not some server mess) and yes it is. I use an ArcEmu server published here in another post (I don't know where the maps/vmaps comes from) and the private server i'm playing on is based on TrinityCore.
So i can't figure out from where it could come.

My last idea was "it's a blizzard bug" so did anyone found some strange necropolis near dalaran's crater in patch 3.2.2a or newer ?

Got lot of screenshots if you want and another strange things : if u touch the wall of the necropolis your direction controls will be totally changed (move forward could make u go left with a strange angle) and you can't cast spell or mount and mobs ignore you (and you can't attack them).
Note : you can go inside with lag, it's like naxxramas lvl 80 uninstanced.


p.s: i don't know if it's the good forum to ask this so tell me if i'm in the wrong section :/ (i though that exploration would'n fit cause it's basically me asking you a question and questions aren't allowed in exploration)
