The roads are only generated in each 100x100 grid in the overmap. They do not cross the grid boundaries. This means there is a high chance the player is going to wander around at the start of the game without any lead where a city might be. This is because the player spawns at 0,0, the center of 4 grids. There is a low probability that a city might spawn next to the player though. It would be best if the cities are connected across grids.
