Even with the proper NFS MW Junkman Editor, users encounter glitches. Here is the fix guide.
| Error Message / Symptom | Cause | Solution | | :--- | :--- | :--- | | "Save file corrupted" on game load | Editor mismatched with game region (EU vs US) | Use a region-specific editor or a universal save patcher. | | Junkman parts disappear after race | Anti-cheat trigger in career mode | Only apply Junkman parts in Challenge Series mode, not Career. | | Car handles like ice skates | Unique Tires + Suspension conflict | Remove Unique Tires.

Use the NFS MW Junkman Editor responsibly. Stick to 1-3 stacks per category for stable mayhem. Beyond that? You no longer own a car—you own a memory corruption vector.
