Dear Masoud_Khodadadi,

Thank you for your post. We have tried reproducing your case but unfortunately, we failed. Here are our steps:

  1. Under the work item Identify Business Goals, create a use case diagram with a use case.
  2. Complete the only step by clicking “Complete” at the bottom right of the work item page.
  3. Under the work item “Manage Epics”, create epics under the only user activity
  4. Re-visit the work item Identify Business Goals, create a new use case and delete the original one
  5. Complete the step again by clicking “Commit” at the bottom right of the work item page
  6. Re-visit the work item “Manage Epics”. You can see the user activity created by step 2 does not exist anymore. New user activity is created from the use case created in step 4.

Are we performing the same steps?

Best regards,
Jick Yeung
