World Guard

This mod is specifically designed to protect your Minecraft world from damage that can occur when changing generation settings or the world seed itself. It prevents ugly chunk borders, disappearing biomes and other issues related to incompatibility between different gaming sessions.

How It Works

The mod remembers key world information during each save, including chunk generation settings, dimensions, installed biomes, used mods and datapacks. Upon the next server startup, World Guard performs a comprehensive check to ensure current parameters match the stored data.

Key checks include:

• Complete world seed match (controlled by crash_when_mismatched_seed=true setting)
• Identity of chunk generator settings and type (crash_when_mismatched_chunk_generator=true)
• Preservation of all previously existing biomes (crash_when_removed_biome=true)
• Presence of all dimensions that existed in the world before (crash_when_missing_dimension=true)
• Matching of biome generation source (crash_when_mismatched_biome_source=true)

Actions Upon Detecting Inconsistencies

Upon detecting any discrepancies, the mod immediately stops world loading and displays an error report. This protects the world from chunk corruption by preventing generation under incompatible conditions.

Forced Loading

If you're absolutely certain it's safe to load the world, you can delete the config/worldguard/backup.dat file from your game folder. However, it's recommended to first create a world backup for safety.

Configuration

All parameters can be configured through the configuration file: config/worldguard/config.json
