After taking Starlight as my headquarters, I attacked Abernathy for food. Initially concentrated on the hired guards and killed them. When the last remaining settler went down, the quest succeeded and I got the message box explaining what happens on success. Also all settlers got up again, drew their weapons, and attacked me and the surviving raiders. This is a reproducible problem for me (i.e. reloading from before the attack and playing the attack again lead to the same problem).
Workaround: Run away. The quest has already succeeded, and the trade route is set up. On returning later everything was calm again. This may be a conflict with something that I have installed, not sure what though as I don't have ai / combat overhauls. The code might need to be tweaked somewhat to go to greater lengths to ensure peace after the successful battle.
