I see many scavengers in my travels and they never really bother me. Sometimes I just blast them for the fun of it. The only unwelcomed guest I have seen in Sanctuary is that roaming trader wench whatever her name is. I wonder how the population would respond to their General and unelected self-appointed Mayor killing a scavenger? I would hate to have to repopulate Sanctuary like I did with that other settlement. Some old hag started moaning when her Brahmin got hit by accident. She whined, "Ahh, it died" and suddenly started shooting at me along with everyone else. There were other Brahmin roaming around. I kept walking away and they kept following me until I finally got mad a laid seige to the whole settlement. Final population was 1 because only ADA stayed loyal to me. Since the last update I notice that whenever I draw my weapon it shimmers as if I was using a Stealth Boy. IDK if it is one of the perks I upgraded doing this or not. I have almost a full set of Legendary Chameleon armor I am carrying but I'm not wearing any of it yet. Glitch maybe?
Not necessarily that scavengers bother you on the road but what they might do in a settlement. My personal preference with scavengers is to eliminate them. I don't trust them. LOL
That roaming trader that you refer too I believe is Carla. I see her at many settlements to include Bunker Hill at various times.
I read that the Legendary Chameleon Armor had some bugs. I don't recall if your problem is one of them but what's to say that it could be tied indirectly to the armor. One way of finding out would be to not carry any of it (store it) and draw your weapon. You may need to reboot the game after you stored it before it will take effect.
