Landmark (emerald graves) bugged, Up near the dragon

Hi

Got dragon age inq, now to run stable without any more DX errors, but when i was out questing tonight in the above zone, there is a landmark right up the top middle of the map near the twisted tree, i can loot the dead body and the chest, but i cant find ANY clickable icons for the landmark at all. 

ok, for some unknown reason it was bugged, reloaded a saved game and its click able. possible issue with looting the chest or dead body
