Thanks for the answer.
I finally found a solution and it will maybe help people.
The file "0112_Bridge_District" is not in the fogofwar folder, because there is no fog of war in this map (all the map is clear when you discover it), but you have to find this file in your save if you open it with a software to decompress files. It is probably the same error for the original author of the post.
Sorry and thank you for the time you took to answer to me.
