Problem completing Water temple quests

I didn't find anybody who had this issue anywhere in the forums, but sorry if I just missed it and duplicate a thread topic. Maybe I'm the only one stupid enough to have this problem.. I'm at the last water temple quest where you have to kill the dungeon bugbears and plant the earth temple robes on one of the bodies. The only problem is that I went to the dungeons first on a killing spree, butchered the bugbears like animals, then went back to town to get some gear and heal and such. When I came back I went to the water temple and received these quests.. but now that I have the robes I've gone back to the dungeon area and all the bodies have disappeared. Am I screwed, or is there some way to finish this quest? Thanks all!

 

Once the bodies are gone, there's no way to do the quest. Sorry. :errf:
I think, though, that you can use the console to make the game think that you have completed a given quest. I don't know the code for that, but I'm sure somebody here does.
