Increase the distance between Survivor spawn and bed allocation.
I've got a big ol' base with a main structure in the center where I have my crafting and such. Just put all the main folks in there to have easy access to their crafting options, but now I can't assign them to their beds in their little houses around the area. Why is the maximum distance between their standing spot and their bed less than the size of the build area? What's the point of having all this space to build their homes if I can't put them elsewhere in the settlement for convenience? Seems really counterintuitive.
