Okay, so this isn't really pertinent to Mineplex, but I don't know where else to find a community of seasoned Minecraft players. So I have a world in vanilla survival that I started gently, and decided to try loading it in the latest snapshot for 1.14 to test out crossbows and pillagers. (Illager beasts are overpowered, BTW.) Of course, I checked the 'make a backup' box just in case. All my stuff was still there. Fine. After I was done, I reloaded the game in 1.13.2 and went back to my world. And all my stuff was gone. My inventory remained intact, but aside from a couple of random fence posts and torches (no idea why those specifically) everything in my world had been reset to how it was when I started the game. So I've found the backup file that was created before I loaded my world in a snapshot, but here's my question; what do I do to transcribe the files back into the game and get all my stuff back? I'm playing on a MacBook Air, High Sierra version 10.13.6.
