Aahh.. How could I be so stupid! Got some help in Hell from some high level players last night (Pala & Druid). When we arrived to the Hellforge quest I got very suspicious. But they been fair all the game and never took any drops from Duriel and Meph. They were standing away from the Hellforge altar so I thought it was ok. When I hit the altar he TELEPORTS up to the altar and take everything and leaves the game. I believe it was a PUL rune. Even though I don't need a PUL it's the disgrace from beeing robbed. How could I be so stupid! I should have known better, and I can only blame myself!
