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)
}
