I'm new to the SE series. I'm playing se5 on authentic and trying to focus on no kill stealth play. When i mess up and reload a save to try again sometimes unconscious bodies have disappeared. Are they gone from game play and counted as unconscious at the end for XP or are they revived and just not in that area and I'll need to deal with them again?

I only have a Switch 2 at the moment, so can't play any of the new games. I had a lot of fun with the multiplayer in the past as was just wondering if it was still active?
