Settlement Survival/Map seeds

Info

 * Difficulty has no change on the map generation as of game version 0.84.217
 * Map size will have minor changes to the map but the spirit of the map remains. Such as the general likeness of the river formation
 * Game version does not appear to affect the seed, as of 0.84.x. This may change with future updates and old seeds may no longer give the same map.
 * Disasters, starting seeds and animals are not based upon map seed but based upon another hidden random seed.
