Molten Core - Unable to enter (Noone can ever enter dungeon now, it's bugged)

Boss, dungeon or raid: Molten Core Character: Cappy Click on Core Fragment -> there is only visual cast Opening no text... but nothing happens, quest does not proc Picture1/Picture2: Entering the Molten Core seems to cause dos on character that wanted to enter, u can see I am of the entrance but second character and also server sees me in the entrance (Picture2): If I click on the object "Core fragment" it says: Out of range (Picture3):

Bug1) 1) Get quest Attunement to the Core 2) Click on Core fragment 3) Nothing happens Bug2) 1) Get into entrance Molten Core 2) Try to click on Core fragment or look at you by second character

On old core: There were no Attunement here in Molten Core neither in Black Wing lair(There is now newly attunement too, also there are gates, but on older core there weren't) On official server: There is possible to get Attunement. Proof: Proof is that player Imas(and also many players) got no attunement to Molten core and got Scarab done.
