It is not game error - the game properly processes the data. I kill him when he run through lot of zombies on NW and they not see him. I shot 3 time. First time he run out in lobby. I think he has about 500 health points bleeding. He return back and die oneself. After 20 seconds he respawn on his body. I helped him to die.The third time I picked up the phone and made a shot i send you. After that I had to crawl out, as he was not one (in my experience you have from 3 to 8 people usually on NW) and his friends began to worry. I'm certainly glad that you do not know anything about the Hacks But as commander you must know it. At the moment there is a possibility nearly a legal way to make yourself in godmod.(ghost in other words) There are also exploits allowing to show in real time everything that is on the server - machines, people, etc. If you do not know - ask your clanmembers. They know EXACTLY.
