Okay I was invading this nice lil institute bunker with my brotherhood and after a fight in the bioscience, there was one synth left. But strangely, he was peacefull, and the brotherhood didnt shoot him. I have mods but none which makes synth friendly to me and the brotherhood. And I didnt pacify him either, I dont have that perk. So why is he friendly? Did Maxon forget we need to kill synths? Also sometimes he holds his gun strange, like in the first picture his hand is not right on the gun and in the second his gun kinda goes through him to the left.
