We are trying to get the final Anomaly in the Encore mission for the Anomalous Voices quest. The one we need is apparently in the Deletion secret chest area and to get there we need to interact with the conflux in the lab where all the dead Chioma's are. The conflux is not there so we cannot open the portal. I can only assume that it's because we have already done all the secret chests prior to obtaining this quest. Is Bungie Help aware of this issue?
