Dimension Fixer

by rostpav79

Dimension Fixer is a Forge tool for server owners that repairs a world left with dimension data from mods that have been removed.

ForgeServer-side onlyAll rights reserved1.20.1

What it does

When a world fails to load after a dimension-related mod is taken out, the server can run Dimension Fixer to clear the broken dimension data and drop the references to dimensions that no longer exist, so the world can start again. Before any change, the tool writes a backup of the level.dat file, which can be restored if something goes wrong. The mod runs on the server alone, so players join without installing anything, and files are published for 1.20.1 only, with 1.0 as the latest Forge file from 2026-07-19.

Key features

  1. Missing dimension repair

    Removes references to dimensions from mods that are no longer installed, so the world can load again.

  2. Backup before changes

    A copy of the level.dat file is made before any edit, so the original state can be restored.

  3. Broken dimension data cleanup

    Repairs damaged dimension entries in the world data without touching the rest of the save.
