Maybe I closed an HQ that needed to be open, or something, but all my other delivery trucks are getting around. But my computer/TV delivery trucks will not leave their garages.
The port is open, space is available, local deliveries are enabled, Computers and TV's are configured for "Export", and other trucks are able to get both in and out of the port, and up and down the streets where my factories are.
I opened a second factory, quit and restarted, closed and reopened the factories, and closed and reopened the individual delivery truck garages, but they just will not pick up their cargo and leave.
