dgun or secomd weapon bug at com?

I try to fire with "D" and click on enemy unit a sunburst or conclusion shell.

But my com try to get closer to get the target in range of it's heavyMachineGun and don't want to fire at high distance.

Notice: I had a PlasmaContainmentField and 7 AdvancedTargetingModules on my com.

Noticed it too with that high impulse long range weapon = cant be used as long range weapon :)

you have a more funny way to describe it - thanks
