Hey Chubby. The way the interface is shown with the builders is not really intuitive and it actually took me 45 seconds to figure out how it works. The game still suggests you what to build on certain tile (farm, mine), but it is shown at the TOP of the pop up window and not at the bottom. The thing is, the cursor starts at the bottom of the window where the row of other actions are (like harvest, pass the turn, move, etc.) So in order to scroll up to build a farm or a mine on that resource, you have to use your D-pad and press left or right until the cursor selects the top button (may it be build a mine or a farm). I hope it helps.
