World Tile, consider changing to ETile. When assigning terrain land and land terrain should take precedence over water. So in the case of world 320km hex 4CG0, or 140, 512 should be a land hex belonging to continental Europe. An island must be a whole hec, except for the straits between it and other land hexs.
