I tasked the movement of my masons workbench when lunch hit. They dropped the bench and went to eat, when they finished they picked the bench up and used it to pave the nearby road. Now every mason I create has a bugged workbench.
Similar situation in a new game involved moving the bench, having it dropped on the ground and picked up like lewt then placed in the workers pocket; however they never can put it down.
I found that if I leave the bugged mason and promote a new town member it will allow them to build a new workbench, yet only if the bugged station holders are still on that job.
