Anyone notice that of the default beds, if you put in the same house, same floor, beds of two different types - the regular full size bed and smaller, narrow cots - that NPCs as they populate into your settlement will preferentially choose the larger beds first?
I made one large beach house on spectacle isle, and put 12 normal size beds and 12 cots in - all one same floor. As settlers started coming in, every single one - the first dozen - all picked the normal size beds first.
