Im sure everyone has seem this in MP.. the invisible guy with his uncloaked weapon running around.. makes for an easy kill, but a bug none the less...

and, I dont know if its me running around all cloaked with my weapon on display as everything seems pretty cloaked to me...

I think it's a known bug because i see in every server a gun flying...
But i don't know why,i don't have this but is annoying to see cloaked guys with a flying weapon...
