I have watched my monorail paths and found that after sections of the rail were removed by the plugin, the monorails are no longer able to go straight ...also, there are remnants of the circular sections of track where they once formed the aesthetically pleasing loops.
I am pretty sure there are other issues as well, as I cannot discern any change in capacities or speed. Actually, my cities become dark with abandonment, likely because the monorail system is forced to take circuitous routes to destinations.
The only way I know the NAM was installed at all is by the presence of a few different road pieces and the aforementioned monorail problem. Clearly this is not working for me the way it's supposedly working for others.
Any help would be greatly appreciated. Thanks
PS. As far as tight circles go, I am still able to build them out of rail....just not monorail
