Bug missing item at auction

Hello!I had an unexpected bug with the auction.When I went to look at it, I sold certain items that I was selling and saw that 1 of my Ancient Pickaxe had not sold.and I decided that I would put up for auction 1 more and take the unsold pickaxe.But!To my disappointment, I could not do this because this pickaxe was replaced with the one that I put up recently and I could not pick up the unsold pickaxe.
