So I recently made two new characters, totalling three characters altogether. I switched save file today to a different character and the game has overwritten one of my character saves, I didn't notice until it was too late and the game had autosaved over that character as well. I decided to then start playing as my first character, to then be horrified by the fact that the game had overwritten my other character when I loaded that game. I'm glad I still have my original character, but this bug has to be fixed by Bethesda; and before you tell me to save manually because autosaves will be overwritten, I had saved manually, the game still deleted it to save my character over it the second I loaded.
I read someone else's post that this had happened to when Skyrim first came out, I never thought it would happen to me. :S
