I really don't understand the way shields are supposed to work.
I know that you need to upgrade them, and I have done so for every game that I've played. But why is there only ever one blue marker in the top left-hand of screen when I've upgraded to 60%?
When I hover over the shields button the tooltip says "Partially Powered, Manned by Crew", but I have 15 unused reactor bars and still the shields don't power up? I appreciate that the additional unpowered bars help protect the system, but I want my goddamn blue shields please. I'm getting nailed at the later sectors.
Why haven't my shields upgraded?
