GPU Particle Systems not showing up once I Simulate/Play?

For some reason GPU particle systems aren’t showing up when I hit play, I’m rending about 10/20k particles

If i turn the amount down and I use a regular particle system they show up just fine.

This is a VR Project

VR on mobile or VR on PC ?

Also, when you have issues like that, it helps a ton when you post a bug report on AnswerHub (preferably with repro steps and a sample project, so that Epic can just see the issue for themselves).

No one will bother to deal with bug reports on the forums.

Thanks for the advice
