Particle System does not render when in built game

I lazily imported a script to have an infinite starfield, because I’m working on a game where there will need to be something to tell the player they are moving at all times, even if there’s no objects for a thousand meters away (which is still my camera’s far clipping plane) and the most obvious being the starfield effect that has been used so many times before, beginning with ELITE. It looks fine in the editor, but when I build the project, it’s gone. Any ideas, anyone?

Ok, I’m not sure why, but it’s just suddenly working again. I built it and it worked. I didn’t even change anything this time.
