I'm using the latest NAM with 5x pathfinding and 2x capacity RHD.
When my avenue networks get big enough, the medians start to flash between R$$$, C$$$, industrial, whatever is contained within the avenue network. The medians flash about every second or so, making the game unplayable. Is this a NAM issue or a game issue? I have tons of plugins running at the moment, but I remember this problem happening to me when I played vanilla.
