Fighting any opponent works until I try selecting the Winged Psychosis Shield. Once I select it and try making my turn, nothing happens. If I then try changing my selection, nothing happens. Even leaving and coming back to the fight leaves me stuck on my turn. I then went into my Armory and switched the shield for something else. When I went back into the fight, the shield was no longer there (neither was the new item, of course), but I was able to continue on with the fight.

Hi. I just went to check and it seems the item has disappeared from my account entirely. :/ Would it be possible to get it back? Or will I need to buy a new one?
