No, i dont have a backup.
I pulled the mod for several reasons.
1.) Lack of a "fog of war" where airbases are concerned.
2.) Made working with the airbase layer a PITA.
3.) Too much clutter on the nav map.
4.) Enemy habors are in red letters now.
Although your certainly welcome to put it back in if you want, it's your game.
The original mod, i beleive, was done by LeoVampire. Just search for mod release threads by him, or threads started by him, it will be one of his earlier posts i think.
