I have a question for someone who already owns the German Upgrade Pack.
In Riot's product description it says: "4 Befehlszeilen auf Deutsch (eine für jeden Spieler)" meaning the 4 player boards. But there is another component that contains even more text and is not specifically mentioned (medium spoiler for those who haven't played the game yet):

The control board for the boss minion.
Does the Upgrade Pack contain a translated version of this item, too?
