I accepted a contract with a neighboring town where I sell a unit of food for 720k while buying it locally only 400k. Everything is delivered by truck. After a few days, I see that I am losing money on the sales with current term sales being below current term expenses.

So I follow the bus during the delivery, and it buy the food at 400k... but it also sells it at that price at the neighboring town (i could see it on the term sale and term expenses). After checking my other delivery trucks, I could see the the selling prices were never respected and that they were also either losing or not making a lot....

Is this some kind of bug? Or is there something I don't understand?
