The Legend of Zelda: Tears of the Kingdom has been updated to Ver. 1.2.1. You can see the patch notes for this update below.
Fixed an issue that sometimes caused the screen to flicker intensely when large amounts of stamps were placed on the Map.
Fixed an issue that prevented players from obtaining the contents of treasure chests attached to Flux Constructs when the treasure chests vanished as a result of the Flux Construct’s attacks.
If the treasure chest vanished, reloading the save data will either restore the treasure chest or cause the chest’s contents to automatically appear in your Pouch.
If a certain event does not trigger when talking to Koltin after collecting all of the Bubbul Gems, downloading this update data will fix it so that the event triggers.
Several other issues have been addressed to improve the gameplay experience.
