NPC showing up later in the game?

Can new NPCs show up later in the game in the already explored parts of the map? I just scrolled over an evac shelter that I’ve already cleared 20 days ago, and a “Dina Crow” now shows up in the map view.

Rescued experiments from labs can move out into the surrounding areas, but I haven’t encountered any new people in cleared areas (apart from scripted ones appearing at the farm once you get the mission to help them establish themselves).

However, I believe there’s a setting for the spawning of new NPCs over time.

That’s what the “Random NPC spawn time” option is for.

Ah, interesting…

yup, in fact most of the NPC’s don’t show up until later
