SubEmitter particles not working in world space

I have a particle system, than whenever a particle collides it creates another one that stays on the place where the main one died, both of them set on world space.

However, I need to be able to control the main emitter position and be moving it around, but the subemitter doesn't seem to work once I move.

Think of it like a water gun, that whenever the droplets (main emitter) collide they make a splash (subemitter), and the water gun needs to be moving around.
