Monument Unlock Quest disappeared without reward.

The team is aware of certain issues with the timed quests requiring Monument unlocks to disappear before players can collect rewards. At the moment, the team does not have a timeline for when a fix will be available, but we can reimburse you the 5 Voyager Keys through a support ticket. If you encounter this issue, please Submit a support ticket with your Support ID and the name of the monument you were trying to unlock.
