I cant load my most recent save. No matter what it is. Every single other save works. Just not my most recent one. Even when I make a new save, it wont work. I still have to load an older one.

Go to Documents>My Games>Skyrim>Saved games. The saved game is there, you have to delete the .TMP at the end of the file name in order for it to show up in the Load Game screen.

I've had at least one savegame (saved from console) disappear completely. Not in saves dir.

I don't even know how to begin diagnosing that.

(sigh)
