hi, im sorry for the confusion, the ugrades are meant to break the game if you get them many times, it adds to the fun imo, and the trains work like this: you get a train to stop, press once to see what they need, then press again to input those items needed, after that, it removes the items from your inventory, the bottom right box, if you need a item, you press right click to open the walkie and press a number from 1 to 5, after the delivery time reaches 0, the item gets placed somewhere on the map and you have to find it, you the just gotta walk on it to add it to the inventory, after all the items are placed in the train it just starts working again, i shouldve added a proper tutorial, thanks for playing anyways!
