Joined the server.
Could not use any doors did not see anyone.
Tried to meet up with my friends, they could not see me.
When we tried to shoot at each other i could hit them with my gun, they could not hit me (i could also not hear or see shots, they could).
I could not use any of my items, dropping them made them dissapear.
Might be important to note that i walked from guglovo to novaya petrovka and then tried to meet up.

I do not know how or when it started. But i assume it was directly at login.
