Old Particles behaviour is not same as current UFE version 2.6.0

For now I need to remove this code and let auto play the particles.

ParticleSystem[] particles = goInstance.GetComponentsInChildren<ParticleSystem>(true);
            Dictionary<ParticleSystem, float> particleStorage = new Dictionary<ParticleSystem, float>();
            foreach (ParticleSystem particle in particles)
            {
                //particle.Stop(true, ParticleSystemStopBehavior.StopEmittingAndClear);
                //particle.randomSeed = (uint)creationFrame;
                particleStorage.Add(particle, particle.main.simulationSpeed);
            }

foreach (KeyValuePair<ParticleSystem, float> particleData in entry.particles)
                        {
                            var mainModule = particleData.Key.main;
                            mainModule.simulationSpeed = (float)UFE.timeScale * particleData.Value;
                            float time = (currentFrame - entry.creationFrame) / (float)UFE.fps;
                            //particleData.Key.Simulate(1, true, true, true);
                        }
