Okay so I am getting the same problem. After about 20 seconds after I activate Infinite health or infinite ammo (only tried those for sure), people start yelling, running screaming that there's a dead body. Even people in their cars are ducking down like somebody is shooting at them. When I take them out the car, they just lay on the ground like they're dead. If you can fix this, that will be great. Thanks for all your efforts.
