Is that a mod or something that allows you to quick save etc?
I never saw a save option except the auto save when you log out at night. But for me it always overwrites the older save file and in the morning, when I log in, I continue where I left.
Having a save and load option like you describe, could be helpful, but honestly I don't know how that would be incorporated in a massive multiplayer game.
Are you sure you didn't just save some settings?
