Return voided item?

When readied up for a raid, I was moving items around in my hotbar and ended up losing my Shiny Raid Won Hero by getting warped into the raid. Is there any way to roll back my character or have the item returned? I was using /itemlock at the time.

I attached a picture, it had around 3300 raids tracked.

Haven't done anything since this happened so I wont touch my account unless a staff member is able to somehow return it or its confirmed that I can’t get it back.

Unfortunately if this were any other item I wouldn’t be making this post but this was the one item Im genuinely upset about losing.
