I figured there would be a learning curve with the truck controls and familiarising oneself with the map, but I'm glad to hear that it does indeed get easier. The deliveries work on a random system, but there is some stuff preset. Certain items can only spawn at certain points and certain items can only be delivered at certain points. And each pickup point has a pool of items to choose from. When it comes to where your pickup point spawns, that's completely random - so I get how it can make things feel unfair. My guess is that it takes some time to learn the right paths, but I wouldn't be surprised if you could get really unlucky with spawns too. Fortunately, that should only be a problem at the very beginning of the game, if it is one. Thanks!
P.S. I was wondering if anyone would notice the radio, since I didn't really advertise it aha.
