Raider - forever! :) (Fallout 4)

Yeah, dear GG, who wanted to become the main boss of the raiders Supplement Nuka-World! This topic is to you!
To you, who is it DLS, fully capturing the Commonwealth.

And of course, I have a question.
1. The capture of the settlement of the Commonwealth for food. Schenk said that the more settlement produce, the more it will provide food for the raiders.

Any settlement should be used for food? What you should pay attention to?

2. Captured one settlement for housing of raiders from the pack (Outpost) - just drove out the settlers without bloodshed, had previously removed the vessels from this settlement, with the Studio pulled out all .....coming in a few days, on the roof of the house is a settler makeup and nothing you can do except pereselit. But you can only relocate in the outposts of the raiders. I had to shoot. Nobody came, of course. The raiders are good. I don't know whether the subject, after some time on one of the outposts (to protect this village raiders) attacked the Minutemen . Which were friendly to me. I had to shoot.

I don't know, maybe roll back that there was this strange settler? Or leave as is? Why suddenly it appeared?
