Knifing

As a knifer, I know when something is changed or has gone wrong. Ever since the Machete update, knifing's hit detection and animation has been way off. Blood will show up, and well after 3 seconds later no damage will have registered. I'll hear the headshot sound effect when slashing, but only a body shot's damage is registered. Sometimes, even, I'll be hit by someone's stab while their knife is still in mid-air! This isn't an issue of lag. Can z8 please fix this issue? It's making knifing really annoying, and therefore, the game is becoming less fun.
