1000 Dungeon & Raid Emblems

Just for clarification: you don't have to loot from every type of Emblems (actually you cannot do this after 3.2). You'll get this achievement, once you loot 1000 from any of the four five Emblems.

Loot 1000 Emblems of Heroism, Valor, Conquest OR Triumph.
Loot 1000 Emblems of Heroism, Valor, Conquest, Triumph OR Frost.

edit: Updated for patch 3.3.

So earned this yesterday, in a pug doing a heroic, at the exact same moment with 2 other players in said pug.

So, i can't even begin to calculate what the chances are of 3 random and utterly complete strangers getting this achievement on the exact same moment in a randomly organized pug..
Very very slim i would imagine.

However, after relaying this story in the guild about this extraordinary coincidence i'm being told that the exact same thing has happened to others as well, leading me to believe that the actual achievement is bugged.

Unfortunately i wasn't keeping track of how many emblems i had collected, it was more than 500 for sure but i cant remember if i was close to the 1000 needed for this one.

I looked up the emblem count on my statistics page on armory and it's actually a lot more than 1000 emblems needed here, so i should've gotten this achievement a long time ago.
Something is fishy here.

**EDIT** Apparently blizz messed something up with the emblem count when they deployed patch 3.2.2, a lot of people lost a whole bunch of them, and now Blizz has *kinda* rectified it with a secret patch setting all people who *should've* gotten this achievement some time ago to 999 so that on the 1st hit they would earn it.
Over here is a similar story for the 2500 achievement.
A lot of people will earn one of these achievements at the same exact time.

There is no comment stating this, but to avoid confusion, this is no longer achievable, since emblems were removed and replaced with Justice Points and Valor Points.
