In order to deliver this feature, there are two paths that diverge. They are both valid takes, and it really comes down to preference. Right now, when something is Transmogrified it keeps the same database ID, which is useful for things like updating a backup copy of a character. That ID is the same if it's in a folder or not in a folder or in a different folder from the source game. But that means that when we add Transmogrify Folders functionality, sending a folder that contains an item that has been transmogrified before (and therefore shares the same ID), we have a few possibilities. Please let your opinion be known by filling out this form for the scientific collection of opinions . I'm going to leave this form open either until April 16, 2026 or there are 280 submissions, which is half the number of votes for this suggestion at the time of this post.
