I think i found a bug on the A26 in France, when driving from Lille to Reims.
This is what the game log tells me:
00:07:19.560 : <ERROR> [fs] Failed to open file "/material/road/asphalt_I_green_fr.mat" in the read_only mode
00:07:19.561 : <ERROR> [resource_task] Can not open '/material/road/asphalt_I_green_fr.mat'
Attached there are two screens of the actual red road and the location on the map.
Keep up the good work, I really love 1.90!
Cheers,
Alex
