Slitherine

In the attached screenshot, I am building a blacksmith, with the bonus for Iron, but there is no visible Iron. Am I confused or is this a bug? (running open beta w/diplomacy)

Nveer mind, I worked it out. It was still hard to see from the resource view of the map, which doesn't show where trade goods have been imported. It turns out I was indeed bringing it into a neighbouring province by 'needing' it with a building, making it available for my blacksmith.
