Something strange

Hey it happened to me something strange while playing CF. Well I pressed join game and i was joining while there appeared the windoy of "disconnected from server" but it continued loading. i was playing as I normaly do, but then i got mutant(i was paying MM) and when someone shoot at me my life was always the same, and in my hud i had the knife even if i was a mutant. Then i realised, that i could kill mutants, but it said that they died from the skull(suicide or failed glitch skull). Then the next round i didn't became a mutant and the i was the only one left as soldier, and all the mutants were arround me trying to hit me, but without succes. when i picked up a supply the minigun appeared, but in my hud i was still with the knife. Before that i thougt it was a hack, because one day i was playing in prisson and someone started to teleport and kill everyone with knife, but he said it was lag. Im only asking if there is a way to remake that error so it can become a hack.

Here is the video.
