The particle module "Event Receiver Spawn" seems to ignore whether the emitter containing it changes from either disabled to enabled or vice a versa at run time.
I also noticed that disabling the module had no effect since the particles still seemed to spawn when the event was triggered.
The emitter gets disabled and it stops spawning white particles normally. However, the particles getting spawned via an event receiver continue.
No white particles spawn after the emitter is disabled
