Reset a ParticleSystem with chidren

I'm trying to reuse a particlesystem effect that has children but for some reason only the parent resets and plays.

I tried Play(true), Stop(true), Clear(true), and even Simulate(0, true, true) then Play(true). None work... I went crazy and even tried creating a loop that goes into each child and plays it, but for some reason it doesn't play the children.

Theres nothing special in the code, i only play it and stop it after some time, then try to play it again
