This issue is likely due to a corrupted Blueprint or a problem with saving changes. To resolve:

  1. Save Correctly: Always save your Blueprint before closing the project.
  2. Check for Corruption: If nodes disappear, the Blueprint might be corrupted—try recreating it.
  3. Recompile: Recompile and resave the Blueprint before closing the project.
  4. Engine Version: Ensure you’re using a stable version of Unreal Engine.

If the problem persists, consider migrating the Blueprint to a new project.
