Issue with Grave Guardians

[Trubo]

Anyone else unable to interact with the Grave Guardian for the quest Stone Cold? The icon to click on them displays as usual but right clicking does nothing. Tried to Heroic Leap/Thunderclap on them to see if I can force some of them to spawn like the Mogu statues back in the Golden Lotus dailies but nothing seems to work.

Edit: bah, should have checked the Blizzard forums first.
