Yes, I went back and edited the title

Think I've managed to fix this, but any other details (what zone you logged into, player faction/level/etc.) would be helpful if you notice it happen in the future :)

Zone: Orgrimmar, Valley of Strength Faction: Horde, Class: Mage Race: Panda Level: previously 60, so whatever that defaulted to after SL - Dunno off top of my head, I think 25 or 30? I dunno what else might be useful? lol
