Niagara disappearing

Hi there,
I’m having a very strange issue where my Niagara effect is disappearing depending on its location. For example, when I have an actor class with a Niagara component using this particular effect, and have the effect as shown in picture one, everything is fine. However, when I change its location in the blueprint to say X = 0, Y = 0, Z = 2100, it disappears when I get close to it, as shown in picture two. Similarly, if I leave its location as default, when I put it in the viewport it renders fine and looks great but it dosn’t appear when I run the game. Any idea why this bizarre issue might be happening?
