If I am hitting the enemies with shield, initially they have it, allright, and I need to breach it to reach the hull.
But after one shield breached, something strange happens sometimes: all shields goes offline after some amount of damages. And no, looking on this ship stats, it still have "shields" not destroyed (only damaged, maybe, but not always). And sometimes this shields goes online on the next round!
My guess is that damaging shields disables them temporarily. And destroyed power generator is the source of "intact, but not working shield" case. Am I right?
2. Most of my bigger ships have stealth+shields equipped. And usually it's stealth initially, then shields activates itself after the first shot.
But some (identical) ships never have stealth - they starts the battles with the shields activated right away. Usually it can be fixed with manually activating stealth and waiting for it to work. (But I have time for that only closer to the end of the battle, and not always).
My guess is that it's the ships that had stealth disabled at some point - because of damaged, refitted or disabled manually. So unlike "standard" disabling because of fire, it's "permanent" disabling, that must be removed manually. But I cannot see this difference with the naked eye.

Question is: can you fix it, disabling "permanent offline" altogether? Or, as alternative, make different "offline" messages for such cases? (Like, "offline" for the temporary case and "disabled" for the permanent, for example?)
3. In one of my boarding attempts I had strange border case. It goes like that:
3.1. I am trying to board shielded ship. "No shield breach found" message appeared. Ok.
3.2. I am destroying shield with the one of my ships. No hull damages. "No shield breach". Oh?!
3.3. I am hitting the ship once more with scout, damaging it for 5-6 damages (no shield reaction was visible). Now I can board!
Question is: what is the reason of it? Some very weak (so practically invisible) shield was active, that slightly affected my shot, unnoticed? Or simply non-breached hull worked against me?
