Ran the last wish raid and spawned in the glittering key chest and opened said chest once we arrived to the location. Once i opened the chest it showed on the right side of my screen that i got the ship but it went to the post master because i had my ships slots filled up. After the raid i got off for the night and the next day i signed in and it wasnt in my post master and i didnt have the the ship unlocked in my collections. My glittering key is also gone, just to make sure that i did actually opened up the chest and didnt imagine opening.
