The quest is on step 5 of 5, Specimen Displayed. When returning to the H.E.L.M and interacting with the glass case, the red gemstone specimen did appear and is currently 'displayed'. However, the quest step did not complete, and I can no longer interact with the display case. I have deleted and reacquired the quest, restarted the game, and waited for a weekly reset with nothing fixing this error. I believe I am locked out of other activities from Echoes until this is resolved.
