Some ideas to reduce the amount of fixing each map needs :

- in the map editor give a different flag to all plain provinces (makes easier to see if you have forgoten to give to some provinces the right terrain type)

- add an icon on provinces with no neighbours (would also make easier to find superposed provinces due to 2+ whites pixels instead of one)

- a general command #nostartif (a number) making nostart all provinces with fewer than x neighbours (avoid to forget some bottlenecks)
