Hi!

I found bug in the Particles System.

1. Set “Engine Scalability → Effects” to Epic
2. Create Particle System.
3. Change “Detail Mode” to High
4. Save and put this particle system in the level.
5. Check, that you see particles
6. Change “Engine Scalability → Effects” to Medium
7. Check, that particles is gone.
8. Change “Engine Scalability → Effects” to Epic
9. Particles still not shown ☹

Hope you can fix that bug. Looks like this bug was in 4.11

Why the f is this marked “resolved”?  
This bug hasn’t been fixed ever.  
Been over 10 years and it’s still present in 5.4.
