Guardsman Stanton's quest text asks for 2 of each item for his various quests... Handing in two of any of the three items works fine, but I could have sworn that on trying to hand in more than two at a time of any of the three items I would only get credit for each set of four, not each set of two. The wiki says he asks for four of each item so maybe this was recently changed to two and something screwy is going on with that, I dunno.
