Hey everybody,

Before i start i posted this in here to get help but also because i might be posting early main storyline spoilers regarding Preston and his group.

But anyways just started playing FO4 and i was thinking about RPing as a hermit in Sanctuary with just Codsworth for company maaaaaybe the dog too. Or possibly even Preston and his friends. But with this particular save game i dont want to have to worry about NPCs attacking Sanctuary. On other save games i'll deal with them, but for this one i just want to build stuff in Sanctuary and sit on top of my house sipping irradiated lemonade and looking at stuff through the scope of my high powered sniper rifle. Are there certain settlement structures that will trigger an NPC attack? like resources for example? or will they show up the moment i start building any kind of structure? If i decide to have a small settlement like just Preston and the initial party will the structures i build to maintain their happiness level bring NPC attacks?
