Steps:
I was doing my Labyrinth of the Ancient runs trying to get items for my Bard. When at the end of the Final boss, Acheron, my group left before my cutscene ended and it forced the item into my armoury chest implying I rolled for it and now I have to wait till next week to get an item. It shouldnt take my chance or even give me an item without me rolling for it. If I can get my item chance to roll for an item back for the week or even an item from the dungeon in return for this inconvenience it would be much appreciated.
The item I received was called "Royal Crown" for CNJ, WHM, and SCH. Clearly I can't use any of those items.
