Duplicate Particles Spawning at the origin

On UE 4.14.3 using VR, we are getting a major bug that came out of nowhere with our particle effects.

When spawning a particle effect, it shows up in the right place but it also spawns at the origin, ONLY on packaged builds. This also happens in non-VR.

We are pretty stumped as to why this is occurring, we were doing SpawnParticleAttached but we also did world location to see if that is the issue. We put a log where we spawn and it never has a location at the origin, but we see the duplicate reliably.

Any hints on what might be causing this or what we can do to fix it?

Thanks!
