Try to turn off all other mods. My mod couldn't glitch your map, because files of the mod don't affect the map. I'm sorry, but I don't know the exact reason for this.

Well, it didn't work. I can still play normally.

Have you tried Verifying the Game's Cache?

what do you mean?

Right-click the game in the Steam Library and go to Properties. Go to Local Files and select "Verify Integrity of Game Cache..." and see if it says that any files are missing.
