Hello there, Thank you for reaching out. A few things to try: Finish the Eris step (if it’s still in your quest log) The weapon comes from turning in the pursuit with Eris on the Moon, not directly from the mission chest. Make sure you’ve completed the step that says something like “Return to Eris” after finishing The Whisper and actually picked up the reward from her. Check Collections (this is the big one) Go to Collections → Weapons → Sniper Rifles / Exotics (or Heavy Exotics, depending on your UI). Look for Whisper of the Worm there and reacquire it. The fact that you’re seeing the follow-up quests for the gun strongly implies the game has flagged you as owning Whisper, so it should be in Collections even if the original drop was missed or dismantled. Check all storage spots All characters’ weapon slots (including on characters you don’t usually play). Your Vault. Your Postmaster in the Tower (if your inventory was full when the game tried to give you the weapon, it may have been sent there).
