Hello @[WK] Ungover_
I will try to solve your problem today.
First of all, if TMP10 load does not appear in any city apply these solutions
1.If you're in a city close to TMP HQ refresh the job list there and try find new jobs for new event.
2.Teleport to TruckersMP HQ and try to get a job there from the tab. When you come to the job page, type TMP10 into cargo and choose one of the two loads that appear there. Choose Haulie Harbor as your destination.
You can check https://truckersmp.com/blog/258 this blog for job dispatcher (if you don't know)
I hope I solved your problem. Have a nice game.
Kind Regards
'Leo.
