Hello,
First at all, you all need to know that my English isn't that good. When I want to build a Sunken Highway, I need to use the NAM. But when I place a "Digger" too make a hole it digs and I can build the Highway. But here is where I face the problem.
When I want to build a overpass, every stone of the "puzzle-roads" is going down with the side wall of the digged hole. Placing intersections is also a problem. It is just not possible. So, what do I wrong, and how can I fix it?
Thank you,
