World Corruption Fixer

_I will port the mod to other versions if this mod gets enough attention._

Removing world generation mods in Minecraft often breaks existing saves and dimensions, leaving worlds unable to load. This mod provides a simple one‑click “Fix World” button that automatically repairs corruption, so you don’t have to mess with manual file edits or complicated recovery steps.

V0. 7 - You can now restore deleted dimensions as well.

Example: If you install a terrain mod like Terralith and later remove it, your world may **refuse to open, Even "Safe Mode" won’t help. Normally, you’d have to follow multi‑step guides online to fix this, but with this mod, you just press one button and the repair runs automatically.

_This tool is especially useful for modpack authors, since it saves players from losing progress when mods are swapped in or out._

_By clicking "Fix World Corruption" Your world will be probably fixed._

``` What does it do? (Technical Stuff)

This mod deletes the "Data" category in your level.dat This causes minecraft to forcefully create a new world seed and use level.dat.old to restore items.

Creating a new world seed doesn't mean your existing chunks are being deleted. The new ones are just generated differently.

For curious nerds: If you open your level.dat with NBT Explorer, you will see the "Data" category. ⚠️ Note: It has not been tested with NBT corruptions, so be extra cautious in those cases.

You can use this mod in your modpack freely. ```
