The second window of the Bakery menu is now Choose Fuel, with no option to choose what recipes the Bakery creates. This prevents the Bakery from doing any work as all recipes default to disabled until enabled.

The baker works by request now. Either request sth from the postbox, have another worker request sth, or set a minimum stock at the warehouse or on the 3rd page of the bakery gui
