Well, one way to get it done is by accepting the fact that codes were placed back when Graal was new. Now, Graal has changed and is going thru some major updates. Shields and swords can still be bought/created but just added to your player inventory very much like how the accessories work. Eliminating the need to have codes from here on. This is the Graal now and players just need to deal with it.

Wish it were that easy.
