Left4Dead2 Visuals Multihack

Why is the usual common dismemberment gore for commons not functioning right while the hack is injected? I tried playing with the hack injected but no options selected whatsoever, with the hack injected and chams for common infected and without the hack injected at all, as in, playing vanilla. And i noticed that the gore while the hack is injected, even without chams selected is, let's say diminished. As if the gore is somehow minimized. No dismemberment occurs whatsoever. No heads popping like in vanilla, no limbs lost whatsoever. You can see wounds on the spots where the commons were supposed to lose limbs or guts, but the body is intact. And i keep wondering why. If this was caused by an option in the hack then i could get behind that. But it ain't. Really missing that good old gore from the game. Was this change implemented on purpose or is this a side effect?

PS: And no, i don't have any addons or launch options that could be causing this.

I think you not on latest version bro. It was a problem in fact but latest vesrion it was sorted. Its the version with the cables bug

In fact i download yesterday the latest version available. That's what i tried all of the above on. And same thing as in previous versions. Did i miss something?
