Fire Emblem: Fortune's Weave, which launched on Nintendo Switch 2, has become mired in controversy over its single-save-file system. Players have criticised the aggressive autosave function, which overwrites manual saves with no separation between the two, making it difficult to undo mistakes or unintended changes in a game requiring over 100 hours to complete. A Reddit post lambasting the design choice has attracted over 450 comments, largely in agreement that this is the game's major weakness.

The issue is particularly acute in chapters with hard failure conditions, where players must reach specific map locations by set deadlines; missing these targets forces a complete chapter restart, potentially costing several hours of progress. Developer Intelligent Systems acknowledged the problem in a Nintendo interview, explaining that a single save system was necessary due to the game's complex multi-path narrative structure. The community's primary request is for the developer to separate autosaves and manual saves into different slots, allowing players to revert to a manual save if autosave compromises their progress.
