Believe in your sylph story quest bugged

My husband and I were playing in a party last night, him on a PS4 me on PC. When we were doing the story quest Believe in your sylph, we both saw the white destination where you do /lookout, but after he did it the point disappeared for me and I'm no longer able to complete the quest. I still see the red circle on the map where I am supposed to go, but the destination point is missing and /lookout will not trigger the event.

Is there anything we can do to get this quest fixed/completed?
