notice the cops still cant find me lol.
I emptied several whole clips into these NPCs that spawn as a result of getting wanted Stars inside the Moc.
after my Moc was destroyed by the cops because they kept shooting at it and I messed up didn't kill everybody in time during the AFK test. Invisible NPC spawns, that's what the military and police are shooting at when they appear to be shooting at nobody. The guy is invincible..... and invisible. until either you drive away and hit a sweet spot or let your Moc be destroyed by the cops, then he will spawn on the ground, and you can then play with the standing still invincible nPC. I've been able to see the NPC on top of my Moc, but only in certain spots around the wanted star areas, and only after I've gotten The Wanted star from within the Moc.
edit: the NPC stays Invincible the whole time invisible or not. If you make him bloody after a while he'll eventually self heal in front of your eyes. No more blood or bullet holes.
Video of invincible NPC on top of the Moc, you can drive this guy around and he never falls off either he may go invisible, but he's still there find that sweet spot again and he will reappear
