I played at monday with three teammates. I walked with one of them near mogilevka while one friend had some desync like 57000. I run away from his position and a copy of my char stands right behind him. (Invisible for me)
He attacks this copy with his fists and my graphics turned into black and white and i take some damage from his attacks. For me it had looked like he punches into the air.
We tried this bug for about three times and i always got some damage, when he was attacking my char copy.
3t Player one stands on the ground while player two with no desync runs a bit away like 50m.
client side hit reg.
makes desync moments strange. but trust me you dont want to snipe at 600m+ with server side hitreg ^^
Same happened me a couple of times. When a guy try to fist fight with me. He was not even close to me on my screen and he hit me out unconscious. I shoot him 2 times in the head with shotgun before he ko-d me (he not died only bleeding) . In close range fist vs shotgun. Fist wins! Tested 0.45 experimental
