I have tried the FogOff mod, but it does not turn the fog off in this mission. It gives an error. I tried adding it to the 0.mi file, but the 0.mi file is apparently not used by the mission in this case. In fact, deleting it has no effect on the game! The game apparently does all the loading from the map.net file, as deleting it causes major problems (deleting some other files does not). Does anyone know how to turn the fog off in that mission? The only way I have figured out to do it so far is to save the game as it starts, exit, open the file in your profile (in My Documents/My Games) and edit the mission file. Search for "Fog 1" and change it to "Fog 0". That fixes it once you load that save.

What version of the game engine do you use? This mod works correctly only under the retail game version (v1.01), because the latest patches overwork the mission files used by this mod.
