Königstiger

I didn't get kicked for AFK, I parked my truck, saved and left. And I suspected that's the case, but I firmly believe that is a silly way of handling things. So I literally can't log out if I have a job, if my intention is to make money and xp (which it is, since I'm doing a career type of thing)

So, last night I picked up a trailer, can't remember destination but it doesn't matter, I don't think. I did have 9 hours to complete the job (in-game time), which was more than enough, but soon enough I realised it was time to sleep so I parked my trailer at a rest stop and left it there. (I might have not parked it in the zone that lets you rest in SP but does that matter?) When I completed the delivery today, it said I arrived late and I didn't get anything at all, not a single € or any xp at all. So is this a design feature or a bug or what?
