For a week now, whenever I cross Pumpkin__King, I would see him shooting nothing.
Here's a video on what I am talking about.
Other people seem to not be able to see his arrows either
He, however, claims that he is shooting "piercing" arrows
Furthermore, I suspect him of using macros since he had displayed similar behavior as did the accused Khajit in the messages. He would occasionally type "m" which is the piercing arrow key.
