erm.. So, if I understand, it's not the targeting NPC problem, just spawn bug. So there's a spawnpoint bug to be fixed, not the NPC targeting system which is more realistic and forces players to invest points into first aid and doctor skills.
Also, I see here a reputation bug, if "neutral" NPC's are shooting at player (of'coz if you have more than -2,5k karma (vilified) in VC for expamle). Not the NPC using VATS system.
