Invalid Save Syntax

[Newsman Waterpaper]

I was adding the SetMapDisplayNameEntry code to all the maps in my mod and trying out the save functions and when I exited the game and restarted it and tried to use the Load Game function, instead of the level names appearing, it just says Invalid Save Syntax but however if I load the file, it will load the map of the most recent save and everything will work as usual. I'll like to solve this for handiness sake for players.
