Describe the Issue

Upon server startup, the console is flooded with warnings indicating that several GlobalLootModifier entries from Supplementaries are failing to decode. This is due to missing serializers for moonlight:add_item and supplementaries:replace_rope, despite their corresponding JSON files being present. This suggests a server-side incompatibility where loot modifier assets are included without their necessary Fabric/common code implementations.

Supplementaries

Global loot modifiers are a forge concept. There's nothing of the sort on fabric. This isn't my mod doing. Report there
