Did you put a building in the wrong place? Or realize that the farmer could be closer to his bountiful crops?
1: Open your build menu
2: Click on Move/Recycle –
Click your building you want to move and it will vanish. You’ll notice the mouse is shaped like a green square now. Click on the square you want to place the building.
NOTE: Upgraded buildings cannot be moved – they get turned into their small buildings.
