axactly this ist the "problem". Your cargo-station 2.2!
This used a 4 lane street-connection, thats seved in the savegame... (forever).
The issue comes with a down/upgrade from 4 lane modern street to country-road.
Trust me... changes in streetconfig and/or street-connection are very tricky.
The first time had my mods installed and uninstalled.
The second time was with a fresh install of the game. My mod was never installed the second time. Again, this is NOT caused by my mod..
If you don't believe me, try it yourself. Verify the integrity of the game, generate a new map "EDIT: in 1950", upgarde the roads to the large road, save the game. Install Placeable buildings v.2.0, then reload the saved game and you will see the same thing. I used the seed xxxxx
