How to reproduce:
1. Open the attached project
2. Open and Play MyScene scene
3. Hit play and observer how the particle plays
4. Now keep pressing sim next frame to simulate the particle over time. Time will be displayed on the bottom.
5. Notice that the particle does not simulate the same way as when it’s just played

Another way to see the issue:
1. Now keep pressing sim next frame until you reach around time 0.21
2. Keep hitting “Sim cur Frame”. This method calls simulate passing the same time (0.21). The particles should not be emitted or look different. But they do.
