I dont think patrols that are deleted in-game are stored anyplace, like the Recycle Bin. If they were deleted manually, they'd probably still be there.
Other than that, I dont think there's much you can do other than grin and bear it, really. Maybe someone else can help you more, or knows something I dont about the game. Maybe a modder? Anyway, sorry to hear about the patrol, I was infuriated like that many a time, usually getting CTDs when my PC was on the fritz. Ahwell, at least you can relive the glory!
