i thought my response was pretty clear.
there are countless reasons why you may want/need to revert back to an old save (that you didn't specifically "name" as important at the time. (bug testing this game would be a fine example...)
i'm not asking the game to permanently save the game every x minutes (auto save) and keep a permanent record of those.
i am asking that any time i manually save, it be permanent.
and that manually saving should not require me to name the save in order for it to reach that permanent state.
this is how most pc games work.
thus why all the outrage here with sims 4, when people find out only after they've lost many saves in sims 4 after they learn this game doesn't work like that... for whatever reason... it's just bound to happen to everyone who buys this game.
