Description

It appears that if you create a Matinee in a Sublevel, and then subsequently move the matinee between levels. It will not keep associations with the attached actors in the Matinee and not trigger events.

Behavior does not appear to be a regression from 4.8.3, however the Warning about confirming you want to delete something does not appear in 4.9.2

Steps to Reproduce

*Quick Reproduction with attached Project*

  1. Unzip Attached Project
  2. Open MyProject3.uproject
  3. Open the Levels Window
  4. Click on Matinee Actor in Level
  5. Right Click on the Persistent Level >> Move Selected Actors to Level
  6. PIE

*NOTE: You can move the Matinee actor back to SubLevel_01 and the connection is still broken, i.e. it will yield the same results listed below*

RESULTS: Particle System is never triggered from Matinee

EXPECTED: Particle System is triggered from Matinee

*FULL REPRODUCTION, including project setup*

  1. Create a Blank Project with NO Starter Content
  2. Create a New Particle System (all default settings)
  3. Save the Level as Test_Persistent
  4. Open the Level Window
  5. Create a New Sub Level called SubLevel_01
  6. Place The Particle System in SubLevel_01
  7. Create a New Matinee Actor in SubLevel_01
  8. Open Matinee Actor
  9. With Particle System selected, Create a New Particle System Group in Matinee
  10. Trigger the Particle System to activate and deactivate across the standard 5 seconds of the Matinee.
  11. In Level Viewport, de-select the Auto-Activate on the Particle System
  12. In Level Viewport, Select Auto-Play and Loop under the Matinee Actor
  13. In the Test_Persistent Level Blueprint, add a Load Stream Level, SubLevel_01, from Event Begin Play
  14. Save all Assets and Levels
  15. PIE, confirm that the Particle System triggers as expected
  16. Move the Matinee actor from SubLevel_01 to Test_Persistent Level
  17. PIE

*NOTE: You can move the Matinee actor back to SubLevel_01 and the connection is still broken, i.e. it will yield the same results listed below*

RESULTS: Particle System is never triggered from Matinee

EXPECTED: Particle System is triggered from Matinee
