The main problem with point 1 is that Piper and Cait keep glaring at me whenever I give her chems (the dislike message appears on screen).
I assume they would have to be temporily relocated elsewhere so as not to encur their disapproval if I chose to do this.
Also, I don't really want to feed her drug addiction.
So far, Sanctuary Hills hasn't been attacked at all.
I assume it's because I haven't installed anything of note, no beacon, no farm, etc.
Two doghouses, a sleeping bag and a bell is all I've added.
If you are curious as to why I haven't done anything with Sanctuary Hills, I won't until I get the mod that replaces this map with the prewar version.
I don't see the point in doing any work on a location that will be removed from my version of the game when I mod it out.
