So, from description every time a weapon fires at a ship, its damage is rolled against armor rating, but every time such roll occures, armor integrity is reduced by 5 %. But in one long battle against precursor dreadnought i've noticed that its armor integrity stays at 100 % all the time as a tooltip says. On the screenshot you can also see it is 50+ phase in a battle. Why is that, is it a visual bug or is it supposed to be that way ?
