I've noticed that when I see an enemy indicator and then kill them from a distance, sometimes they are "Merchant" or "Merchant's Escort"...not sure if this is intended, do bandits have such NPCs in their groups? I also noticed that the Merchant ("Malachy") at the Deserted Settlement goes hostile as soon as I approach. I have read that this merchant can be interacted with and items bought, so I'm wondering if I did something to trigger hostility or if it's a glitch.
