Cloned NPCs/Won't get in car (week one mod)

So I keep running into this one glitch where my starting roommate will somehow get cloned- as in all of a sudden, there's two NPCs following me with the same name and sometimes similar outfits (at one point I had 3 of the same NPC). They also can't seem to figure out how to get into a 4 seat car; even when I went out of my way to go find a four door, I still get one yelling ''wait for me!" and running against the car.

Is this just a glitch? Do I just leave them behind? (i like having the extra npcs for protection, even though they usually end up dying from defensive NPCs) Also I'm playing build 41.78.7 in case that helps
