When you type the "`" you are enabling the "console mode". After that you must type "toggle_fow" for turn Fog of War disabled. When this occurs, the console must disappear i think.( i never use them in this game). Then you must type "`" again for enter in console mode and type "toggle_fow" to re-enable the Fog of War. But if you have an error trying for third time, is probably that the game as a bug or not support a recursive command. Other thing, ¿you disabled the option that says something: See the Computer's movements?. With this optios disabled, the computers no show you the tour over the whole map. Like in MTW.
