I am not sure how to save custom data for a saved game yet, so units will load as just regular fortified units.
To counteract this for the time being, I added a function that should set fortified units to guard when the game is loaded. I found this less annoying than trying to find all the units I had on guard and reset them when a game was loaded.
Updated Fortified Alert 1.11
Added Guard command in new experimental version
