Sometimes you collect a better card than the one you already have in the book, and you have to open the book and extract it to equip the new one, it would be good, after clicking on the card, instead of throwing an error that you already have the card equipped, show dialog box if you want to replace the equipped card and upon confirmation, make the corresponding change, it is also good from replace equipped cards that are from the old system, and that have to be removed manually
