Users at TL3 are able to recategorize topics, or so it is stated on the Badges / Regular page, as below:
This badge is granted when you reach trust level 3. Thanks for being a regular part of our community over a period of months. You’re now one of the most active readers, and a reliable contributor that makes our community great. You can now recategorize and rename topics, take advantage of more powerful spam flags, access a private lounge area, and you’ll also get lots more likes per day.
However, on May 4, 2022 (yesterday, as this is being written), I tried to perform such a recategorization, with rather unfortunate results. I had noticed a request for help that clearly would have been appropriate for the Users category, but had instead been posted in the Core Workflow category. I clicked the edit icon to the right of the title and used the pulldown menu to change the category to Users, but poof! - the post has effectively disappeared, except for its URL, title, and new classification within Users, which, evidently, the system still remembers. See below:
For convenience, here is the URL, copied from the screen capture:
I have seen this happen before on another Discourse forum.
What can we do at this point to recover the post?
This matter is currently of special concern as we are discussing the possibility of splitting the Users category, which would then require recategorizing some of the existing topics.
