Multiple Particle Emitters disappearing

Just wanted to report this in case anybody ran into the same issue I did. I had problems where multiple instances of a particle emitter (in my case a texture sheet emitter for fire) was disappearing and reappearing (along with all of its particles) seemingly at random.

To fix the issue, I created a unique material (each using the same image) for each new particle fire I made. It was tedious but seemed to fix the problem.
