Me and my wife were able to open the Elusive Faerie Cache, but we received nothing.
I was finally able to loot the chest today! There is a WQ in the area, which seems to have phased the chest in for me properly. Wanted to let folks know.
Able to click the treasure but received no loot as well.
Update: Loot was sent to mailbox after a few minutes but issue still stands that loot didnt pop up when opened.
