Save file corruption

For some background info this save had 160-180 hrs of my gameplay and I had completed so much more than on my first gameplay which I had sped through ng 1 2 and 3. I had so much more weapons and armor or just completion in general. I defeated pretty much all mainline bosses right up until consort radahn which is where my problem began. So one night I was maybe 3-4 hours deep into attempts and I was good to do maybe another hour or two and had no plans on stopping. On what turned out to be my final attempt ever on that save, is what corrupted my file. I remember I had just pressed the button to walk through the mist but right after pressing my character walked far enough to where I could only see the mist and then my power cut out because of a storm. I figured it was a sign telling me to go to sleep and so I did. What I wasn’t expecting was that the next morning my save file had become corrupt because it got interrupted. I made this post to cope I guess and I was wondering if anyone else experienced something like this. I’m really bummed out even though this happened months ago. I’ve tried making a new file but don’t have the same joy in me starting all over again after losing that much. End Rant.
