So, recently I ran into an issue with my save disappearing. I have been running the most recent 1.9 snapshot (15w51b for those keeping score), and had a couple of power losses & other crashes. On a couple of occasions, all my work was lost.
I did the customary search online, and saw all the usual tutorials and guides about all the steps needed to salvage my map, and then I wouldn't have my inventory that I had lost. So, I simply thought to myself "there HAS to be a better way!"
Turns out, there is.
I simply navigated to the Saves file, and found the usual files, especially "level.dat" and "level.dat_old" However, I noticed that "level.dat_old" had a file age only a minute older than the "level.dat" file. So... I moved the (corrupted) level.dat to a temp folder (the desktop on my Win 10 system), and then renamed "level.dat_old" to simply "level.dat" Loaded up Minecraft, and my corrupted game had returned.
Now... The best part?
My inventory was still there!
In fact, it was as if I had just closed the game out the usual way. The only difference was that when my game shut off, I had just killed two zombies on the other side of a fence from me (they were annoying), and I was placing some blocks for a build I was working on. Instead, the zombies were back and the blocks I had placed hadn't been placed yet. In game terms, its as if I had jumped back in time a minute or two.
This same issue happened later, and the method of fixing it was the same, with the same jump back in time a minute.
Apparently, Minecraft is continually auto-saving by renaming "Level.dat" as "Level.dat_old" (overwriting the old _old in the process) and then saving the Level.dat. At least in my case, this has been happening every minute or so. Your mileage may vary.
