Bulge '44 Map: Why no Trails?

[bdtj1815]

The decision not to have trails on the map was a mistake. Two obvious examples: In the north, trails that were part of 12.SS PD's Rollbahns leading to Krinkelt-Rotherath are not present. In the south, the trail CCR/7th Armored Division used to advance into Bastogne during Patton's relief effort is not there.
This can lead to certain villages not being depicted on the map, though why Losheimergraben in the north is omitted escapes me. Maybe extending a stream too far north to Losheim so a blown bridge could depict the blown railway bridge is the reason this bit of the road net looks off. (A tank ditch would serve the purpose.)

Some years ago I made exactly the same comment about the missing trail in the 12th SS area when working on my Bulge scenario. Unfortunately did not get anywhere. I was not aware of the missing trail near Bastogne but have checked that area and the trail used by 7th Armoured is missing.
