It’s working !
Thanks, hert ! The reason it didn’t work was a tiny piece of road that was missing between the truck station road and the road into town. Corrected that and in came the oil. 😉
Both trucks are supplied by one truck station at the oil well. The production of the oil well is at 40 now.
Great to know because a situation like this, where there’s only one oil well or ore mine and 2 or more refineries or steel mills in the neigborhood is not uncommon.
Onwards to the next challenge. 😉
