Deleting unused engines in sandbox bug

Found this when cleaning my engine list and accidentally deleted all unused engine when I didn’t intend to. Here is how to reproduce the bug:

  1. Click “Delete unused engines” in sandbox
  2. Click “Keep”
  3. Delete a single engine
  4. All unused engines will be deleted

Thanks for reporting. Are you opted into the Al-Rilma open alpha, or are you in the main public branch of Automation?

I am opted into the open alpha, however I believe that can happen in the main public branch too
