It is glitched for most people. It seems that the game thinks you already have the ghost yet you don't have the card. The same holds true for the ghost under the stairs in the basement of the ship on the Forgotten Shore (the room with the level 18 Knights and the Celebrant of Oryx). These are the last two legit dead ghosts I need.

Question. Has anyone had issues finding ghosts *again* after already finding them? I've found the one in the area where you fight the gate Lord for his eye while doing patrols and exploring. Then took friends there while doing the mission for daily or whatever it was 2 days agoto show them since they hadn't gotten it and it was there for me again
