I recently returned to playing SC4 and one of the first things I did was to install NAM (April 2008 edition) on my Mac. I carefully followed all the instructions, installing all the essential files and one plugin each from the Traffic and Automata Controllers. All the NAM content seems to work fine. However, an issue has arisen with commute times. My Sims' commute times immediately rose to 25 minutes and have stubbornly stayed there, even for journeys of less than a dozen tiles. My city is tiny, only a few thousand strong which makes this impossible, not to mention undesirable. For the record, I installed Plugin A-Hard from the Traffic file. If anyone has any advice about what's wrong and how I can fix it, I would greatly appreciate it.
