Steps to reproduce:

1) Download package "BUg.unitypackage", make new project in Unity and import this package.
2) From Project tab, drag GameObject(1) prefab in to Scene/Hierarchy tab.
2) In Hierarchy tab, click on GameObject(1) >> Cube >> Particles(1) >> Ground_Moving_Left.
3) Check if Emission for Particle System in Inspector tab is set to Time (see attached image "Time.png".
4) Press F/double click on Ground_Moving_Left(Hierarchy tab) object to focus view.
Note: Sometimes it focuses to the object, sometimes to wrong position.
5) Change Emission to Distance and it will act the same as with Time.
