[Sarkhan]

in this quest http://everquest.allakhazam.com/db/quest.html?quest=233 when I tried to combine the <You then need to combine an "Iron Rod", "Forging Hammer", and your "Trooper's Pike Head" in the forge to obtain your Trooper's Pike> it came up with an error..

It said "this tradeskill can only be performed by shamans" and then it locked up all my hotbuttons and i could not open/close bags or inventory or use any skills.
