Iron not showing up in the stockpile when collected.

[stiles]

don't forget the small refinery and smelter are very helpful early in game to process that iron ore. glad you found the problem. now your pile is probably full of rocks. over at WOB slink made some nice small markets to store the stone and take pressure off the piles. the other thing you can do is adjuct your limits up or down so the workers don't over stock an item. should be an arrow with a line over it icon to get you to the limits.
