KoS any idiot pulling that kind of crap.
But seriously now, you can't expect morons to not abuse such a glitch when it was discovered so quickly. Popular places would obviously be bombed due to ego-craving maniacs. I'd suggest using pearl. Killing those sobs whenever you see them would also be beneficial towards your satisfaction(as they gain some from dropping the wings), seeing as how they(possibly) annoyed the community before with other bugged items.
