Automatic route is kinda busted. Truck automatically takes the first items on the dock, regardless of where they're supposed to go.
This shouldn't be the case. They take the parcel for their destination. Unless something is full and parcels must be exchanged.
I have had the same problem. Automatic route from location A to B ends up getting filled with location C, E, F parcels and then it just bounces between A and B.
hi. I have updated the game to give more controls about which parcels the trucks can take. It should be better now
