Is there a way to get easy crafting/construction to also apply to smithing?
The game has a few things that require elements to be able to perform an action, unless there was a way to fool the game to believe everything possible was in your inventory which would probably break the game with how terribly unstable it is already, I doubt it.
Crafting smoothies (needs base ingredient but not the others) and upgrades need their base requirements met before executing.
