Playing on Xbox Series X. Just went to make another save, and noticed my previous manual saves showed "Data corrupt!" I opened Load Game and all the autosaves said "Data corrupt!" too.
If I try to make a manual save, its saves in about 2 seconds...but the icon is still spinning in the bottom right. After about 5-10 seconds of spinning, the file name changes from my quest name to "Data corrupt!" Hours of progress about to be gone due to this.
