I really don't want to have to travel around to each settlement every time they're attacked, nor do I want to waste time having to building defenses. If they want to be defended, then instead of scattering to multiple small "settlements," they should be populating one of the actual towns I keep clearing out. Ridiculous. Anyway, what happens when you don't go defend one when it's attacked? Also, If I store an item at one, but don't go defend it, will that item still be there?
