When the mod generates recipes for compatibility, such as for Create, those generated recipes are put directly into the "data" filepath, rather than a "recipes" filepath. This is inconsistent with vanilla Minecraft as well as every other mod, and makes working with the data unnecessarily difficult.

For this example, the recipe id should be "alloygery:recipes/compacting/copper_double_ingot"

All of Alloygery's recipes, as well as compatibility recipes, all exist within the recipes sub path. When viewing the recipe ID with EMI (as shown in your screenshot) "data/namespace/recipes/" is not included in the path.

Take the following vanilla crafting recipe as example:

Notice the recipe ID is not minecraft:recipes/copper_block

You are correct, idk how I missed that lol
