Just wanted to let you know, The update said Equipped items or Hotkeyed Items (assume that means the ones that are in a weapon set, but not being equipped at the time).
But it also gives you the confirmation for Customized Items.
I had an old character with the Nolani Wand (+5e always wand from collector outside Nolani), and I deleted that character some time ago, and saved the wand in storage. I noticed a few minutes ago that it was customized for that character so useless to me now, and went to merchant it. I got the confirmation "Are you sure you want to sell fire wand?" screen

So the update is more broad than they let on.
