Describe problem (what you were doing / what happened):

I noticed this while making recipe changes, but just did some comprehensive testing with every single spell component - some will accept recipe modifications but a majority of them will not. It isn't formatting errors(I've checked all of that) or wrong item/file names to my knowledge, some spells just will not change.

It's interesting to me that some spells do work fine with changes and it doesn't seem exclusive to whichever secondary items I'm changing in the recipe itself, which makes me think that they're all meant to work with datapack modifications.

I've put together a testing data pack where I changed exactly one ingredient in each recipe(they're all unique from things used in any other recipe chosen somewhat at random, though I don't know if the uniqueness actually matters or not), if you'd like to see for yourself how only some changes apply when the format is ostensibly correct.

I know crafttweaker support exists on 1.18.1 now(it wasn't quite there yet when I first noticed this data related issue), but still thought it might be worth mentioning that the data pack route is only about half functional.

Quick list of which components can be changed through data packs and which cannot based on my testing:

Works:

• Poppy
• White Tulip
• Pink Tulip
• Sunflower
• Rose Bush
• Nether Wart
• Chorus
• Radiant Daisy
• Flare Orchid
• Midnight Bloom

Don't work:

• Blue Orchid
• Allium
• Azure Bluet
• Red Tulip
• Orange Tulip
• Oxeye Daisy
• Dandelion
• Lilac
• Peony
• Apple
• Lily Pad
• Poisonous Potato

All work correctly but you weren't overwriting them correctly. The issue is your folder name was incorrect, it's not recipes/components/COMPONENT_JSON it's recipe/component/COMPONENT_JSON

Weird that some of them still worked then, but okay.

I believe it has to do with load order and some other weirdness. It's best to use the same folder structure to make sure yours are the ones minecraft uses.

It's odd, I was having issues getting component recipe changes to work even with the correct format until I put the changes into a separate data pack and loaded it alongside my other general changes and also removed a change I'd made to the brazier recipe in either data pack. Not 100% sure what was at fault there but it's working now so I won't complain.
