Hi there,
For some reason the Emitter Extents does not affect my particles. I just see my tiny little particles in the middle of the scene. This only occurred when I refreshed the tab. When I change the values of the Emitter Extents the box does not expand accordingly.
Any ideas what could be causing this?
I think it was a little bug in the editor.
Seems like toggling the component to off/on fixed it. 
Ah, interesting. If you have a reliable reproducible bug, can you please log an issue here please?
Then, I can assign it to @Elliott who has done some really awesome work on the particle system codebase recently.
