I'm finding that the NAM is breaking a lot of transportation pieces. Case 1 Rail networks no longer work and RR Xings (normal) cause streets, roads, avenues to become broken meaning cars cannot use them. Case 2 Avenue intersections are broken meaning cars cannot use them. Is there a way to only include the pathfinding and speed/capacity upgrades found in the NAM while omitting the fluff that breaks objects that we previously perfectly functional?
