Small issue with the route advisor: the left side of this highway is not discovered (unless driving from the opposite side, i suppose) and the green arrows -or at least that's what they should look like- are bugged. [ external image ]
This is most likely not a bug. You will find that situation several places. Both on the 'vanilla' map and on the new DLC-map.
It just means that you have to pass that bit or road in both directions for full exploration. Just as some of the filling stations, where you have to pass the same bit of road three times to get everything explored
Yes, it's a section of road where it splits and merges. There's actually two one way roads.
While logically the roads should be discovered in both directions it's a downside to the way the map is built right there and the alternative is less desirable.
The green arrows are placed at the nodes, at the split and merge the "direction" of the road is "wonky".
