I really love Transport Drones by Klonan.

However, it always drove me crazy that I would have 1000's of "Road" items left over in my storage network after upgrading to "Fast Roads".
For some reason, the default recipe does not require the prior tier "Road" to produce "Fast Roads"

This mod alters the recipe of "Fast Road" to require "Road" and also adds "Iron Stick" as well - It made sense in my head...
