Hi! I tried to search for this but the search does not seem to work, it did not display other topics. 
I just played the second Dread Lord Campaign mission and a new core design was available. It has 1 Laser and 2 Laser II installed and when I hit "Upgrade" the component tooltip shows all of them do 1 Beam Damage. But the summary on the bottom shows only 2 Beam Damage. But it should be 3?
Name: Star Fury M2
/Edit:
just edited another core design and it seems some components are just for decoration and are not working (like sensors or basic support, they don't take up space but are in the installed components list). So it is no bug, just a "cosmetic" laser gun without doing damage? Or do these additional systems start to work when they fit in after researching miniaturization?
