I was cleaning bp and there was some blue shoes that i double clicked. I thought it just changed my boots but my berserker exotic 80 ones is just lost.
That’s odd! I imagine it’s somewhere. Have you checked all your characters and every storage bin possible? This doesn’t sound as if you were near a vendor and accidentally sold them. I just have a feeling they’ll turn up if you look in every nook and cranny. If not, contact Support by filing a ticket through the “Ask a Question” tab on that linked page and they may have other ideas.
