Errorless crash upon playing game with an emitter present

[InfernoSuperNova]

I'm having a really, really strange issue. At the moment, emitters straight up aren't working, but they were working a few hours ago. I've tried a ton of things, but I just cannot determine what has changed. I can play sounds via script, but if I have an emitter with an event set, it completely fails and causes the game to crash upon load, with no errors or anything.
I'm running a double precision build, so that perhaps might change some things.

Update: this only occurs with emitters that existed in the tree at the same time as the Fmod Bank Loader
