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. 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 also make sure you've completed the Gilded Treasure and One Man's Trash triumphs. If the issue persists, please capture a video highlighting the issue and upload it to YouTube, then send us the link. We'll be glad to pass it along to the developers for investigation.
