Errata
by Tomma
Errata repairs recipe grants and advancements in NeoForge worlds so that modded recipes appear in the recipe book as expected.
What it does
Errata targets two recurring problems: mods that ship recipes without a matching grant advancement, which leaves those recipes hidden in the recipe book, and mods that ship advancements written for older formats where removed item or tag predicate keys leave empty conditions. Errata rewrites the broken advancements into the correct syntax through a generated datapack, and mods with working progression are left alone. It runs on the server only, so players join without installing anything. The license is MIT and the code is open source. Files are published for NeoForge across 11 release versions, 1.21.1 – 1.21.11, with 1.0.0 for 1.21.11 as the latest.
Key features
Recipe book grants
Recipes that a mod never granted are given through a generated advancement, so they show up in the recipe book.
Advancement repair
Advancements written for older formats with removed predicate keys are rewritten so they trigger on the next matching pickup.
Targeted fixes only
Mods whose progression already works are not modified, so the changes stay limited to broken grants.

What the author says
Mods routinely ship recipes without the advancement that puts them in your recipe book, so those recipes stay invisible forever. Others ship advancements written for pre-1.20.5, where the removed item/tag predicate keys leave an empty condition that matches every item, so the recipe unlocks on your next pickup…
