The fact that the resources don't show as added to your stockpile probably means you've been crafting with them. Check your crafted items after you get back on after a while of being off.

As far as I can tell, if you mine, say, 1000 coal and create 200 graphite (5 coal each) then your stockpile will show no change, but the game will report that you gained 1000 coal (which you don't see in your stockpile because it was turned into graphite).
