A woodcutter working at a wood cutters building will chop logs into firewood. Firewood is used by all citizens to heat their homes. Without a heated home in the winter, citizens may freeze to death.
When there are no logs in the wood cutters inventory, he or she will travel to the nearest stock pile that has logs and bring them back to the building. The worker will then cut the logs into firewood.
After firewood has been cut, the wood cutter will pick up the firewood and store it in the nearest stock pile.
