Why does a line renderer component messup the editing handles? (stealth tutorial)

Hi all, see the image below. My robotguard is in the centre of that sphere. the sphere is a collider for determining his vision range.

As can be seen in the image, the editing arrows are a few metres off to the right of him, and not at his feet as i'd expect.

I've figured out what's causing it. The gun he's holding has a child object (fx_lasershot) which governs the FX for firing, and fx_lasershot has a LineRenderer component.

The parameters of that can be seen here: (in the below image, the robotguard is about where that white lightbulb on the right side is)
