Minecraft – Why did all of the items disappear

minecraft-java-edition

So today I logged onto my minecraft singleplayer world and all my items (including my armour and chest items) disappeared. The weirdest thing was all my item frames were knocked off the walls, the chests were still there (just empty), and all the signs said really weird stuff. Here's one example:

null
"dyes and
dye ingredients"
null

What's going on?

This has happened to me. When you open a world in 1.8 (or any post-1.7 snapshot), it changes the way the data is stored (tile entities, blocks and inventory data). This means, for example (using Torches): 50 becomes minecraft:torch.

When you open the world back in 1.7, Minecraft goes "What the heck are these?" (minecraft:torch) and therefore deletes it, as it is not recognized as a block/item/whatever. From there, you would find blocks such as signs/chests (item with TileEntity data) and items in your inventory missing.


The only way you can get your world back is to restore a backup (if you have one), like I did.
If you don't have one, then you'll have to start all over again, as there is no going back once you've opened the save. But if you have a windows 7 profesional you can restore an older version of the file.
