problem with setting pitch and bank

[{USI}_Zombie 0]

I am using setpitchbank.sqf available here and it works great, but I am seeing an interesting effect:

notice where my crosshairs are aimed, and where my bullets are actually hitting. This is just one effect of setting the pitch and bank I have found. Trying to move over or through objects causes collision with them, but interestingly enough, only on the host computer. I collide with an invisible area of the object but my friend does not when I host. His shots appear to be hitting low and to the right of his aimpoint though. :confused: :confused:
