First of all hello! I'm very sorry if this issue has been brought up before and/or fixed. I've searched through google, oddly enough I didn't find anything. Maybe it was just my poor choice of wording, but..
For the last couple of days I've been playing minecraft. I started a new world and made a fair bit of progress in it. Today when I loaded the game, it was not on the ''worlds'' list. But my two older worlds were still there. I went to the .minecraft folder to check out the save files, it was still there.. (I've had similar issues, with servers disappearing from that list, but that's not why I'm here.)
Anyway, so that's basically my issue? The save file for it is there, but it's not showing up in my worlds list for minecraft. I'm not sure what kind of other information I'm supposed to supply here, but I can actively answer any questions.
The world won't show up if the level.dat file is damaged / corrupted. This must be what happened to you.
The level.dat contains information about your world (seed, your inventory and location, settings). Restoring a backup will preserve your world settings, but revert your inventory and location.
Replacing the level.dat altogether will result in ongoing weirdness as new chunks will be generated with the wrong seed / settings.
It all depends upon what you've been doing with your world, and what's the most important part about it.
If you know the seed, etc. It may be that the level.dat file can be repaired. Or maybe level.dat_old isn't that old and you can use that.
First thing you should do though is make a copy of your save, so you can get back to this point after attempting to make repairs.

Thanks for your help.
