Particles Not Facing Camera Bug.

I keep getting particles that look like this. Where they are not facing the camera.



This is how it looks in the editor (paused at the same frame)



Here you can see the smoke is set to billboard.



The odd thing is that this is happening for most of the particle effects in the game. i.e. you can see the fire doing the same things. I thought this might have something to do with running int he editor but I get this in release builds too.

Any ideas what would cause this?

Thanks

 

I isolated the problem down to the Dynamic Decals package from the Asset Store version 2.0.2, when I upgraded to 2.0.3 this went away. As soon as a decal appeared on the screen this happened. It seems to have deeply disrupted the particle system. I may by worth investigating why two unrelated systems would malfunction like this. But for right now I am fine.

 

I think the layout does not look good for some reasons
