Timewalking Dungeon Credit Not Showing on Great Vault

If your Great Vault rewards appear to not include your Timewalking dungeon progress to choose from during the week after you run them, it's possible the rewards you are seeing is from a previous week.

Great Vault rewards will remain until you choose between the available options. To see additional weeks of rewards to choose from, you must make a decision about the previous week of loot first, and then open the vault again.

If multiple weeks of rewards have not been chosen, you may need to loot the vault multiple times to get to the latest week.
