Legion Assassins cause merchant to turn hostile

[Maniac3020]

So, I'm walking alongside this traveling merchant when one of those Legion Assassin squads shows up. Even before I fire the first shot, the merchant next to me is turning around and attacking me. So is the lone merc who was limping along the road towards me.

 

Why would the unnamed, faction-less npcs turn hostile when the legion shows up? The only mod I'm running that seems like it could be causing it would be Project Nevada.

IWS-Core.esm must be the problem
