I mean the ones within the settlments by a supposed settler.
I wasn't able to resolve even a single one of them. I get the message of the settlement being under attack, travle there and find a dead settler lying on the floor. Lotting them produces a synth component and obviously the other settlers and defenses already disposed of them.
But the quest is still there, in my log. I just spent a week at Egret Tours to see what happens. In short, nothing. When I left, next thing happening was the good old "failed to defend" message. Travelling back reveiled a serious drop in happiness and destroyed defences, water purifiers and crops.
And that's how it always goes. Regardless of location, If I see a single settler lying around on arrival, my next thought is not again. Has anyone been able to resolve these attacks?
