Item disappeared
From the Wiki: The Jotun star fragments only drop once. Afterwards, you can sell them. It is not necessary to have them in your inventory to complete The Jotun Star.
If you continue to have issue, you can contact the CS Team via the ‘Support’ link above/below and ‘Submit a Ticket’ for assistance.
Good luck.
