World Guard
by CorgiTaco
World Guard protects an existing world from generation settings that changed since it was last loaded, so chunks and biomes stay intact.
What it does
When a world is loaded again, the mod checks whether its world generator settings differ from the ones used the last time. Changed settings are kept from reshaping existing terrain, which helps prevent missing chunk walls and biomes that would otherwise appear after a seed or generator change.
The mod runs on the server only, so players join without installing anything. It is published for Fabric, Forge and NeoForge, with files for 1.21.1 only, and it is not open source; All rights reserved applies.
