Winter Labor
A simple mod which changes otherwise inactive workers to be laborers in Winter: Foragers and Arborist buildings become disabled and all crop fields are set to 0 workers. Five days before Spring, they are all returned to work without having wasted their time twiddling their thumbs. You are able to modify the days before they leave for winter labor, how soon they return, and whether foragers and/or arborists stay at their workplace through the winter.
