The unloading mechanic for the MAN trucks is very very difficult to get working properly. I've tried on flat runways or dirt and it prevents me from unloading the containers. I've managed to get the container to unload a few times but more often then not, even if I don't move the truck, it prevents me from unloading in the same spot. From what I can tell, there is no rhyme or reason on when I can or cannot load/unload. Both with mods and only 3CB vehicles/requirements. is there a fix or workaround?
