The niagara particle emitter spawned via verse are not destroy when stopping a session in-editor.
The issue is observed via the spacial profiler tool - note that the objects are observed on the server.
Replication of the bug can be done using a similar verse script:
using { /Fortnite.com/Devices } using { /Verse.org/Simulation } using { /Verse.org/Assets } using { /UnrealEngine.com/Assets } using { /UnrealEngine.com/Temporary/Diagnostics } test_issue := class(creative_device): @editable Particle : particle_system = VerseAssets.NS_Particle OnBegin<override>()<suspends>:void = { spawn{BugLoop()} } BugLoop<private>()<suspends>:void = { Sleep(1.0) loop: SpawnParticleSystem(Particle, GetTransform().Translation) Sleep(0.01) }
