Blizzard have addressed a bug where players who bought Coffer Keys from the Delver’s Journey for 2,000 Undercoins did not receive them. They are also sending out said keys to players, so if you ran into this issue, try logging out and back in to receive them.
We’ve recently sent out the Restored Coffer Keys to those who were affected. If you don’t see them, logging out and back in should make them appear.
