no, i know where it is because i did it in beta but like a fool i forgot to talk to him twice and just killed him. my perceptions at 8 and i tried a boosting spell but am not able to locate it myself. just wish the quest would go away.
You dont need to physically see the mound where you can dig. If you know where the loot is all you need to do is "equip" your shovel in your weapon slot while standing above place where you wanna dig. Solved this quest this way, too .
