Dj Sona Ethereal Icon Not Displaying

So, Dj Sona's Ethereal Icon is IMO the best icon I own. So I always use it. I logged on today to see it wasnt displaying. I checked the list it was a blank square there. I checked my friends lists, they dont have it either just a black square. All other icons are fine D: MAH ICONN is it just me? or is this like a bug >_>
