Hi, I started playing SC4 a few weeks ago, this site has had lots of great info and I can usually find answers to my questions already posted.   I just installed NAM and it seems to be preventing me from connecting one-way roads in an intersection.  I use a grid layout of two one-way roads in opposite directions with one space in between., and after installing NAM I have problems re-connecting my roads if I bulldoze anything.  Sometimes it just wont let me connect the last road in the intersection at all, and I have to fudge the connection.  Other times it works just fine. The pic with the industrial zones shows "before.  Then I bulldozed some roads to put in a landing strip, and tried to re-attach them afterwards, and they don't connect. Any idea what the problem is?  Has anyone else experienced this?  Is this just because my city has "legacy" roads that I built before installing NAM, and the old and new roads don't mix?  Or is there some sort of special tile that I have to lay to make this work properly? Any advice would be greatly appreciated.
