i also had an equally lucky moment. after a crushing defeat in one battle in which i tried to save one of my planets, i tried to savalge what was left of the battle against an advent fleet with 3 Revelation class ships, about 15 cobalts and a level 8 Kol capital ship.
8 of my 15 cobalts made it out safetly (the rest got slaughtered in the powering up phase). but my kol, which still had 2/3 health left, kept getting some sort of spiky beam around it and it couldnt movee, probably got stopped by the revelation class ships) r. so by the time it finally got out of the danger area, it only had 42 health left.
it lived to fight another day... only to get whipped again.
