I have been working on the Statue puzzle for weeks! But my dang villagers wont finish it, I'll quit out of the game for a day when there are 12 hours left leave it on 2X speed and come back the next day to find only 5 minutes progress has made and all the builders have been shircking their job and eating and the Chief has gone to help the researchers!!! Does anyone know how on Earth I am meant to complete this puzzle?

Also I've got about 15 villagers working on it.
