Many high tier items needs an item that item need an item. This is very tedious and annoying. So why not if you click on an item and you don't have the necessary item it gives you the option of smart craft, where all the ingredients and ingredients of the other items are added together alongside the time to craft.
This will remove the need to lock items that at your point of the game are technically ingredients.
Kinda overpowered but easy to nerf just if using smart craft it will take 20% longer if you crafted the items one after the other.
