Hi there! Thanks for reaching out. If you haven't acquired all of the Encryption Bits yet, make sure you've collected all region chests in the Pale Heart in addition to searching all of the rubble piles in the Cyst activities. Please note that we are currently addressing a separate issue with the triumphs incorrectly tracking region chests and rubble piles. Therefore, please don't rely on these Triumphs as confirmation that you've collected all region chests and searched every rubble piles. We recommend players to re-run all of the Cyst activities and make sure every rubble pile has been searched. Once all of the chests and rubble piles are interacted with, you will receive the Lost Encryption Code regardless of how many bits have appeared in your inventory.
