I wouldn't play with settlements just yet - wait for the hotfix patch. I (and many others) have hit showstopping bugs both with current settlements and the new autophage settlements. e.g.
- No Overseers office
- Missing settlement terminals
- Settlements with no inhabitants
- Autophage settlements missing roofs and other structures
- The new autophage items missing textures or looking low res
- Settlement event countdown timers running out but does not complete or trigger new event
- Cannot add materials to constructions projects
