📋 About This Mod
When saving the game, ModSync will take a snapshot of your currently installed mods (name and version). Then, when loading save files, the mod scans the current mod list and compares it to the snapshot of the save that is being loaded. If differences are found, loading is temporarily halted and you are shown a warning that lists all differences, which will then wait for your decision to continue loading or cancel.
The snapshot mentioned is in the respective save file's folder:
Game folder\SNAppData\SavedGames\slot<slotID>\ModSync.json
Adding, removing, and updating mods may not always be safe during the same playthrough. ModSync makes sure you don't miss any change, which is especially useful if sharing save files with others or if you're reworking your setup.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Handy for keeping track of mod setups across multiple saves
- Small but active user base (43 endorsements, 1,930 downloads)
- Recently updated (December 2025), so likely compatible with current game version
⚠️ Cons
- Low endorsement count suggests it's not widely tested or community-vetted
- No mention of compatibility with specific mod managers or load order tools
For players who juggle multiple mod lists and want a safety net against accidentally loading a save with the wrong mods. Skip if you only use a single stable mod setup and never switch things around.
💡 Beginner Tips
- If you use a mod manager, install ModSync through it to keep track of its files automatically.
- After installing, load a save to see the warning in action—it should appear if your mod list differs from when the save was created.
- Keep ModSync updated to ensure it works with the latest game patches.
