Guys I am using NAM 48 in SimCity 4 on mac, and I am trying to add a raod over rail at 7.5m elevation. But the the puzzle piece of the rail remained diagonal no matter how I rotate, but on youtube tutuorials I saw that the puzzle piece actually has orthorgonal rail puzzle piece. I tried avenue over rail and they worked just fine. Is there anything wrong with the installation of NAM? Thanks!
