Loot from broken hearts disappeared from inventory

I was in my brother’s game and his xbox disconnected. When that happened my game crashed out and the sniper rifle from the event disappeared from my inventory. It’s a great weapon for my build - any way to get it replaced?

Were you reconnected when you checked again after the crash, or still disconnected? You might need the current hotfix applied to enable these items. If you can confirm that the item went missing after the crash and remains missing even with the hotfix applied, your best bet would be to file a support ticket
