You must have installed and activated the DLC. Notice: This mod doesn’t work without Special Transport DLC. * In order to get oversized cargo jobs that do not have special routes, you need to advance the time by sleeping several times in the game after installing the mod. – Oversized cargo jobs now have two options, with special routes and without special routes. With this mod, you can deliver oversized cargoes on Special Transport DLC’s own special routes without speed limits/escort vehicles!
