Emitter Explosion not exploding

[Iszard]

Hey Community,

I just updated from 2.5.0 to 2.7.8 and now my emitters don't explode anymore. They produce there particles and them which live for there desired lifespan but don't move anymore.

var em = game.add.emitter(0, 0, 10);
em.makeParticles('SBCollectibles', ['StarOrangeParticle.png', 'StarPinkParticle.png', 'StarYellowParticle.png']);
em.setXSpeed(-300, 300);
em.setYSpeed(-300, 300);
em.gravity = 500;
em.start(true, 500, null, 10);

I rolled back to 2.5.0 and work as expected

If you use v2.7.9 it should also work.
