Particlesystem only emitting once

Hey guys I am currently stuck on a very weird bug.

I have a three-part particle system (three particlesystem parented under each other -> not using sub-emitters ) which I set off in code. Everything works well..no problems playing it in the editor during runtime and such. But when making a build of my game the particlesystem only emits particles the first time I "play" it.

I have already tried/checked many things:

• scale is 1

• I added a bunch of non-sense just for safety measures

    if( particle.isPlaying )
    {
        particle.Stop();
        particle.Clear();
    }
    else
    {
        particle.enableEmission = true;        
        particle.Play();
    }

• I know its entering the function and such

• sorting is taken care of (they are always on top of everything)

• a bunch of other stuff I have already forgotten

Anyway..help would be very much appreciated as I am currently not sure what to do next. Every other particlesystem works fine.

Thanks in advance
