That's a good idea, Nightingale. If that's set to 0 enemies 'should' die even if they're somehow set essential by the engine (though it means companions in normal games will also die if they're shot up too much, so it'll only work somewhat invisibly for players in hardcoe mode). If the enemies going unconscious is due to something else than the game thinking they're essential, though, it might not work.
As for archive invalidation, let's hope they fixed it from Oblivion so that it actually does something now - in Oblivion the engine didn't even read that text file or something, if I remember right.
i had to reinstall, or rather i just gave up tring to find out why i couldnt launch the .exe, so in the middle of that, if it works it works.. if not
bust as for companions, in game hit ~ click the companion, type setav health 999999999. dont need to worry about them dieing again... ever lol.
