How to Restore old save

[MystiK`]

So here's the situation. I last played minecraft months ago ( w/ mods ) and I recently wanted to play again. Now I had problems with the Scala lib. once I got it starting again all the mods are the same. for some reason it loaded the world where I got my base but it had no progress whatsoever. It like set me back to my old save how do i restore my old "most recent" save like before I stopped playing like last year on december

P.S. there are some new saved files...maybe overridden some old....how..halp ;-;

time table 
last played save is on december 28, 2019 but I remember playing on january 2019 ( but i couldnt find any folders with that date )

then some new files were created last October 7,2019 my most recent file, the world where I was sent back

So you're asking how to un-overwrite a world save that you didn't back up?

You cannot restore the save if it is gone.

However, if you made back-ups, then you could use those.
