If you get a request for 1 furnace. The warehouse have a stack (Important stack) of 23 furnaces. The DMan comes and grabs the ENTIRE stack even though the request is 1 furnace. He goes to the builder and delivers ALL 23 furnaces to the builder not just 1 as requested.

Should be fixed in the newest version, should be on curse in a few minutes
