5 probs - i wallhack , the game exiting, scarlight prob and Game Exiting suddenly

the first one is that i "wallhack".
well i dont try to, i didn't bought any hack or something, it just that in certain angles i can see through the walls a walking an enemy or a ghost...
I will upload a replay later if needed... [it happens quite rarely [Once in 10 rounds] but still happening.
The Game exiting, before 17 hours [yesterday night] i played and suddenly i couldn't join a server because an unkown eror, lol wdf?

yesterday i played a few GMs with JamirJamir and N [maybe they has a replay] and my crosshair, everytime i switched to my scar bag was 10 times bigger then the normal dotted circle.

Before 2 days i played Z.M and the drunken game just stopped... happens alot lately.

and the other thing, is when im lagging i am just shooting anyone and the game counts it as a goldenheadshot...


replays / pics? If needed
