Combi Overloader will not auto unload

[cstukins]

I have not been able to get the auger wagon to auto unload into my semi using the combi overload and transfer mode. The course works as expected all but when the auger wagon gets to the wait point at the semi it just sits there and does not auto unload. I have to stop driver and press "R" to unload and then drive course. What are the possible issues for me to look for. I've done everything I know to get it to work.
