Virtual Villagers--Clean Well

Just logged on after starting a new game and my Villagers cleared the well. I also lost one when he saw a face in the trees and went to investigate, never to be seen again. He had been working on building a new hut. I moved another villager, who still wasn't doing anything, to building it, but then realized I needed to get some tech points so I could start farming so he is now on the research table. Have three of my remaining adults chain ganged at the research table while the last one keeps foraging for food.
