This is a bug present in both vanilla and RGON at the moment. Due to this bug, it can cause modded items with high qualities to be crafted with oddly cheap recipes (ones with only coins and red hearts, etc.). I think it would be more intuitive, if possible, for modded items without their crafting quality set to default to a crafting quality equal to the item's regular quality.
