Stability & Explorers

[p]A quick update today to fix some issues caused by the changes to the map (this should prevent any random turn of the month crashes people may have been encountering on old save files).[/p][p]I've also changed the Explorer trait which used to give the ability to chart paths for free, it now unlocks the entire map regardless of whether you have visited a city or not. This probably takes it from the weakest overall trait to one of the strongest early game traits.[/p][p]Enjoy![/p]
