any reason?

why someone is unhittable while they're killing with first person?

Sorry for no videos.

It's a bug with this latest release. It's probably the worst bug so far with 0.4, it's certainly the most critical one right now. Alot of people are now starting to use it as an exploit and they're abusing it to avoid all weapon damage. Unfortunately alot of server owners don't know about this yet and still allow it on their servers. And the bug doesn't happen when you are in FPS mode, it happens during the transition from 3rd person mode to FPS mode. Basically, if you're about to get shot all you need to do to evade the damage is quickly switch to FPS mode and then switch back to 3rd person view.
