For all projectiles and warheads. Not really a must for everything else, but for CreateEffectWarhead, the ImpactTypes refactor (separate PR) makes it a bit harder to make the warhead valid in every situation, so setting the victim scan to zero is the easiest way to disable scanning for actors completely.
