Am I the only one running out of wood and steel? I feel like I haven't even really built THAT much except in 4 of my 7 settlements...but I keep running out of EVERYTHING.  

Wood.
Steel.
Copper (Obviously)

I make a point to scrap everything I can in every settlement, and to collect as much as I can from around the map...yet I still keep running out of supplies.  Am I missing something?
