Hello. Please check all characters in game including the vault, do not look on the website/app. If it is nowhere to be found, then unfortunately it cannot be replaced. Also to note that Bungie does not handle third party applications and websites, so any other questions would need to be answered from them. Bungie does not replace in-game items that are lost, discarded, or consumed. ([b][url=https://www.bungie.net/en/Help/Article/12211]Deleted Item and Character Policy[/url][/b])
