this is sorta a game changer, we use this function all over the place. Maybe you've wondered why a PB goes off and it didn't hurt you, when you damn well knew it should've, or maybe never noticed when a kami was supposed to do more damage than it did, a sentry wasn't killed when you tried to splash-damage it to death, etc.

I just put that patch into WFA and am gonna test it out, but ioquake3 is about to come out with a release.
