Hi there! Thanks for reaching out. If you haven't acquired all of the Encryption Bits yet, please make sure you've also searched all of the rubble piles in the Cyst activities. Please also double check that you have fully completed the Gilded Treasure and One Man's Trash triumphs. 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.
