Many users found that when they scanned the Wolf Link amiibo in Zelda: Breath Of The Wild the on-screen companion would be summoned with a maximum number of hearts. The way in which you were meant to get these was to complete, or at least progress through, the Cave Of Trials found in Twilight Princess HD and then the data would be mirrored to Breath Of The Wild.
The new update fixes this issue and now deals out the correct number of hearts.
The same update also ensures that arrows that are fired towards you and are obtainable are limited to just 20 and players can no longer enjoy a limitless supply of them.
Well at least we know what Nintendo mean by “adjustments to make for a more pleasant gaming experience”.
