We just completed the raid. All six of the raid party had three raid keys (conduit, armoury and drain)going into the Final fight. Upon completion three of me and my party no longer had the keys. Not in our vault, other characters... nowhere This was super disheartening as we just finished the raid and were ready to pilfer all those loot chests. Would love to hear some sort of solution for this cause it's 3 raid level chest down the drain.
