Shield Disruptor Can't Shoot Uphill?

Not sure if feature or bug, thought I'd ask.

So the shield disruptor apparently cannot shoot up a hill/plateau, not sure the exact logic, as seen in this image. I can shoot at the red (civilian) shield disruptors on the ground straight North just fine, but not the Eastern one on the plateau. It simply will not fire.

Thanks in advance.

I don't think it's a bug. With a SlavedToBodyArcRange of 5, a TurretPitch of 0, and a TurretPitchRange of 20, I wouldn't expect it to shoot up or down at steep angles from flat terrain.

I will complain that it does shoot down from the hill just fine, which is unintuitive.
