First time using SS. I started a settlement in Sanctuary and after 9 residential spots, it won't assign settlers to them. Settlers also aren't being assigned to work related plots. I have City Plan Limit off and it says 15 in the lower left of the hud. Auto assign, auto assign unique, and auto assign away from beds are all on. I also refreshed all plots. I don't have a city plan right now but I have codsworth leading it because I was just trying different things to see if something would get fixed.
