World Corruption Fixer Mod FAQ
10 questions players actually ask, answered.
Where is the Fix World Corruption button?
The button appears in your singleplayer world selection menu, next to the world you want to repair. You'll only see it for worlds that the mod detects as corrupted from removed terrain generation mods.
Will I lose my built structures and buildings?
No, chunk preservation keeps all your previously built and explored areas safe. Only unmapped terrain that was generated by the removed mod will be regenerated with a new seed.
What happens to my items after the world is fixed?
The mod uses backup data files to restore items where possible, but it focuses on world generation issues rather than deep item data problems. Items in containers or on the ground in old chunks should be preserved.
Can I use this instead of Minecraft's Safe Mode?
Yes, this mod works when the standard Minecraft Safe Mode fails to load a corrupted world. It's designed as an alternative solution for worlds that Safe Mode cannot recover.
Do I need to manually edit files or use command line tools?
No, the entire repair process is automatic and one-click. You don't need to edit game files or follow complex recovery steps yourself.
What if I remove multiple terrain mods at once?
The mod can handle multiple removed terrain generation mods in a single repair. Select the corrupted world and click the fix button; it will detect and repair all terrain generation issues.
Will the new terrain look different from my old world?
Yes, unmapped areas will generate with a new world seed, so the terrain in those regions will be completely different from what would have generated before. Your old chunks remain unchanged.
Can I undo the repair if something goes wrong?
The mod creates backup data files before repairing, which it uses to restore items. However, the world generation changes are permanent once applied, so back up your world file before clicking repair if you want a safety net.
Does this mod work with modpacks that swap terrain mods?
Yes, this mod is specifically designed to protect player progress when terrain generation mods are added or removed in modpacks. It lets you safely switch between different world generation setups.
Will the repair process affect my game performance?
The repair itself is a one-time process that happens when you load the world, and it shouldn't cause lasting performance issues. Your world will load normally after the repair completes.
