save game, retire and watch replay - map, for a low resolution reveled map, load saved game.

Pretty sure you need DebugMode enabled or something.

Building scouts and walking them around the hidden areas of the map has worked for me.

Just install and use IGE, When you see what you want, you click out of it..restart your game and the fog will be back.
