what armor could stop them?

I was attempting vesta overkill with a laser ship and railgun ship, fighting the drones before the capital battle, when both of my ships crews were simultaneously killed. There was no fire coming their way. Both ships were spinning extremely quickly after. It seems to only happen when I am viewing the enemy fleet/drones for some reason. Any idea what’s going on?...

when was the last time he gave a sign of life?

Is there a way to unlock all the missions

I have refueled the cargo ship and driven the fuel ship back，but I can’t end this level
