I don't know if its with the new anti cheat or if its the server, but for the past few spawns I've been running around then I've been getting punched to death and I cannot see the person attacking me at all.
I verified it by running and then looking around to see if anyone was following me and I don't see anyone.
One particular instance I saw a player rubberbanding around and punching me to death while I sat there trying to catch up to him to knock him out.
