I don't know if this is the place to ask this, but since i'm on a mac I use Félix Cloutier (the online thing) and the first 5 layers work ok, but after that it says that it's building roads, but I could be waiting for as long as 3 hours and still no roads are shown. It seems as though once it has to start generating the roads, it gives up. Does anyone else have this problem? How can I solve it?
