I've read dozens of times that this shouldn't happen and it was declared as a bug in the past if I read stuff on reddit
about that topic. I don't know if it's intentional or not, but at the end of the video (last attack)
you see after the zombie lunge attack, I'm scratched.
Can a lunge attack or it's meant to scratch you at some point? I tried it also "with" clothes, same result if I try often enough.
