Unlike linear shooters, Far Cry 4 auto-saves constantly. It overwrites your single save slot every time you complete an objective, fast travel, or die. Once you finish a mission, you cannot replay it without starting a New Game or reloading a pre-mission backup. For completionists, speedrunners, or players who simply loved the “Durgesh Prison” escape, manual save files are the only solution.
