Particle Sub Emitter Bug 5.5.3f1

Hey,

I made a particle effect with a sub emitter, in the editor it works perfectly, in game 10% of the time the sub emitter won't fire, is t$$anonymous$$s a known issue in 5.5.3f1 or did i overlook somet$$anonymous$$ng?

The sub emitter is spawned on birth with a burst of 1, i never had any issues before.

Any suggestions?

Edit: It happens on a new particle system with a single sub emitter, both are set with a burst of 1, the sub emitter doesn't fire 100% of the time.

Edit 2: Giving the sub emitter a 0.01 second delay on the burst settings seems to solve the issue, i'm a bit tired of making detailed bug reports so i'll just leave t$$anonymous$$s information here in case it helps someone else.
