:lady_beetle: Bug Report – Undo All Deletes Files Instead of Reverting Changes (macOS)

Product: Cursor Editor
OS: macOS (Apple Silicon / Intel – observed on Mac)
Issue Type: Critical – Data loss risk

:red_exclamation_mark: Problem Summary

When multiple files are edited and I use “Undo All” (or equivalent bulk undo action), instead of reverting the changes inside the files, Cursor sometimes deletes the files completely from the project.

This causes unintended file removal rather than rolling back edits.

:repeat_button: Steps to Reproduce (Observed Behavior)

  1. Open a project in Cursor on macOS

  2. Edit multiple files (add/remove content)

  3. Trigger Undo All (or bulk undo for recent changes)

  4. Instead of reverting content → files get deleted

:white_check_mark: Expected Behavior

All modified files should revert to their previous state (content undo only)

:cross_mark: Actual Behavior

Some or all edited files are removed from the filesystem

:police_car_light: Impact

High risk of accidental data loss during normal undo workflow.

:pushpin: Additional Notes

• Happens specifically with multi-file edits
• More noticeable when working fast across many files
• Standard undo per file works fine — bulk undo triggers the issue

Please investigate — this can cause serious project damage if unnoticed.
