I keep running into instances where two hostile factions are spawning near each other. Legionnaires keep spawning by outdoor vendors. Whenever I approach the area the Legionnaires start gunning down all the vendors. Im a PC user so I can fix this with the console but I would rather not keep doing it. It would be nice if you could remove the Legionnaire spawn point next to the .

I've never seen Legion over there. Legion spawns in my experience are almost exclusively closer to the river or near the road between Nipton and Novac.

Ditto to this. I don't even know a spawn point near there for Legion troops. O_o

Was it an assassin hit squad?

Stuff like this used to happen in Fallout 3.
It seems bad guys have a habit of "respawning" where they were last killed.
Thus the raider who had followed the player into Megaton would respawn in Megaton.

To get them away, draw their attention and lead them away from novac, preferrably to the east.

Nope. Im Neutral to the Legion.

The way respawn worked in Fallout 3:

- NPC or critter initially spawns in at the marker that is placed in a CELL using GECK. They then start their patrol pattern, or normal activities based on their AI package.

- However, respawn occurs at the location of their corpse. They will then start walking back to their original spawn point and resume their normal patrol / activities. Unless their AI package causes them to aggress on another NPC/critter.

I used to draw the raiders north of the Pentagon entrance over to the Brotherhood of Steel guards in Fallout 3. Every 3 days, the poor souls would re-spawn and immediately draw aggro from the BoS. If I was feeling particularly cruel, I would drag their corpses up and put them right next to the BoS. Just to make sure they couldn't get away before they got cut down again.

So, after the NPCs die - drag the offenders as far away as possible. Preferably in a direction towards which they will start walking away from the problem location. This may take a bit of observation or knowledge of the area to know which way is the best direction.

It's all Mr.House's machinations, only he decides where NPCs may spawn.

The only thing I have seen close to that is Legionaries and NCR soldiers spawning close to each other and of course a large battle errupts. 75% of the time the NCR wipes them out.
