I absolutely love this game but can someone please explain the postal routes? I first chartered additional routes assuming I could put parcels for any of the routes shown on the map that day (3 routes since I bought the deluxe upgrade)- I got penalised for 'wrong destination', so then I got another charter and just selected one route (the red route), but then I still got penalised for every parcel because they weren't on the blue route, even though I had both the blue and the red on my map, and all aprcels were on the red route? Help!!
