The Shadow Of The Beast

Hi guys. I've got a problem. I do the quest " The shadow of the beast " and i'm arrived at " Kill the beast and return to Dereg with the three pieces of evidence of the beast's existence at [-1483, -5218] ". I go to this coordinates, and i found Dereg.. Now, i have in my inventory "Escaped Cow Eye" and "Piece of BigFoot Bone"... I think something of quest, is missing and this quest has any BUG!! I tryed with /fixquests, but there is not an item for this quest... Please, tell me the reason of this problem, and if is it, tell me how i can find this "missing item".. HELP!

Post Scriptum: I'm Italian, and i know my english is Bad :P

 

I would recommend looking up a video for it on YouTube.com

 

You need 3 items to finish the quest: Bigfoot's nail, hair, and bone. One of them is dropped by Bigfoot, and is probably an untradeable item, whereas the other two will be quest items and are given to you by NPCs. They might be in your bank. Make sure you have all three. The escaped cow eye is from that triggered farmer, and is worthless.
