When you see the error message, you can go to the journal menu and search for the Dungeons reset button. Once reset, you will see all available items to complete the quest.
Method 3: Manually Select Quest
Sometimes, the issue of items missing is due to the fact that the game is not able to register quests automatically. This can happen due to multiple reasons which are out of the control of the players. But do not worry, as you can manually go to the game journal and select the next quest. This will automatically mark the previous quest as completed.

When you find all the items for the quest, log on to the game journal. Here go to the quests menu and manually start the next quest. This will automatically mark the previous quest as completed and register the items you have collected so far.
If you have multiple gaming consoles or PC, then its methods will fix most of your issues. You can log in to both devices and complete the mission on a console. This will register the progress to your gaming account, and then you can log back into your PC game and start a new mission.
This method can b tricky at times, as the game might not register the progress always. But if you have multiple gaming systems, then do give this method a try. If you don’t have multiple gaming systems, you can also use your friend’s gaming setup.
Method 5: Check Integrity of Game Files
The issue of the Diablo 4 missing pieces bug may arise due to corrupted game files or processes. This is very common in online multiplayer games, and thankfully, Blizzard and Steam have an easy-to-use system to verify the integrity of their game files. Here’s how:
For Steam users:
- Open Steam and select “Library” to view the games.
- Select the game that is not updating and right-click the mouse to choose the “Properties” option.

- A new tab appears on the screen. Select “Local Files” to continue
- Click on the “Verify integrity of game files” option.

- Let Steam verify the game files.
- Click on “Close” once the scanning process is finished.
The process might take anywhere between 5 minutes to 20 minutes. So sit back and let Steam verify the files for you. Once done, please restart the game and see if this helps.
For Blizzard Account users:
- Launch the Battle.net client on your PC.
- Now, click on the particular game icon that you’re trying to repair.

- Click on the cogwheel icon (settings) next to the Play button.
- Select Scan and Repair > Click on Begin Scan.

- Wait for the repair to finish. Once done, close the Battle.net desktop and reboot the PC to apply changes.
This method should resolve the game files missing or corrupted issues completely. However, if you cannot fix the issue, we recommend you uninstall and reinstall the game.
If none of the above methods help you much, you can raise a ticket to game support. As sometimes the issue can be account-specific, they can help you out positively. To raise a ticket, log on to Blizzard’s official website, go to the customer support section, and raise a ticket with the game name and complete details. Don’t forget to add the error screen screenshot so they can help you faster.
