Unable to delete level with Particles

The bug occurs if any actor has UParticleSystemComponent with particle Template set.

Steps to reproduce:

  1. Create new project
  2. Create new actor (BP_TestActor)
  3. Add Praticele System component to it
  4. Set any particle
  5. Create a new level (TestLevel)
  6. Place in it BP_TestActor
  7. Try to delete TestLevel.

During deleting error pops up.


The bug was reported here [UE-81574][2] but my steps are simplified because I don’t need to use the child actor component.

Does anyone know how to work around this?

The workaround is to delete all actors on a level prior to level.
