Exploit fixes

I made a couple of videos to show the two exploits:

**Vehicle Spawning Exploit:**

**Ragdoll Bypass Exploit:**

I used "FAdmin slay" in the ragdoll video but it could be anything that calls Player:Kill(). A more likely, but more accidental, scenario is when the Hunger Mod is used.
