When using together with "Recipe Essentials" from someaddon, NERB doesn't seem to work (the recipe book is still there, which makes me assume that NERB's other features don't work as well). Both mods are on their newest versions available for Fabric 1.20.1.

Reproduce:
Just install NERB alongside "Recipe Essentials" from someaddon (only available on CurseForge) for MC Fabric 1.20.1.

Hi. RecipeEssentials completely overrides any modifications to the recipe book's UI. Since this mod also covers about 65% of what NERB does, you have two options:

1. Use RecipeEssentials' configuration to enable all features related to the recipe book. NERB will handle the remaining aspects not covered by RecipeEssentials.
2. Simply remove NERB.
