I have been playing for over 60 hours. I've never shot a settler, unless they were a synth. I returned to sanctuary hill to drop off my junk. A settler asked me to take care of some raiders at the satellite station.
I went and took care of them. Upon returning it is night tone and none of the settlers are in their beds. I found a large group behind the house. They all go red and attack. Preston is there and isn't aggressive.
Any ideas what happened?
