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 and searched all of the rubble piles in the Cyst activities. It’s recommended that you re-run all of the Cyst activities and double-check every rubble pile. After you’ve interacted with all the intended chests and rubble piles, you should receive the Lost Encryption Code, regardless of the number of bits that have appeared in your inventory. If you're still having trouble, please make sure you've completed the Gilded Treasure and One Man's Trash triumphs.
