Magnum Opus quest is soft locked for my account. Cheater had popped into tower and dropped exotic quest items to all players in the lobby. I had not completed any of the required steps to get the Anomalous Object quest item and in receiving it, it soft locked the magnum opus questline. I cant use the strange key because destiny servers has labeled my account as having acquired the quest item already. Need a dev to reset that Anomalous Object acquired quest flag so I can proceed normally.
