This happens on a bunch of people, it's not from the Pitt. I have no idea what causes it though. Don't laugh, I have read here on the forums that it can happen to YOU. :cryvaultboy:
It's never happened to my character when I used the Auto Axe O.o
But it's hilarious XDD His ENTIRE left hand was stringy, but his right well...Thumb and two forefingers were long, but pinky and ring fingers were short.
