Mystical Realms Data-Pack

A server-side datapack that silences errors caused by other mods' own broken data, so you do not have to install the heavy optional dependencies those mods expect.

It works by overriding the offending files: each broken recipe, advancement, loot table or biome tag from a third-party mod is replaced inside that mod's own namespace, so the mod's file never loads and the error never fires.

It adds nothing of its own. It never touches, and never requires, any mod of ours.

The idea in one paragraph

Several mods ship data that errors out when an optional dependency is missing, or that is malformed in their own right. Cataclysm Spellbooks, for example, ships 26 recipes that reference items it never registers, which produces hundreds of cascading "broken recipe" errors. Installing this datapack replaces those files with inert stubs inside the same namespace, and the errors stop — without you installing Ice and Fire, Biomes You'll Go, or anything else.
