moderated Weird topic-locking behavior in a particular group #misc #bug


Hi Mark,

Something weird may have gotten inadvertently introduced today, this just happened on a group of mine.  It almost looks like the system locked-topic notice gets sent or posted to the group as a new message (and topic) when I lock a regular topic.

I locked a topic and all seemingly happened as usual, except a message was now somehow sent (or just posted) to the group, containing the usual system notice:
The topic you're attempting to reply to has been locked by the moderators.  If you believe you still need to reply to it please email the admins at with your reply message text and explaining why you should be able to reply to that locked topic.
Thanks You.

And there is more weirdness about this:

- There's nothing in the log regarding this stray message, just the normal topic-locking entry for the original topic.
- A new topic with the same title as the locked topic gets created.  If I unlock and relock that same original topic, another notice gets sent to the group and it now threads under the newly-created stray topic.
- I can lock that stray new topic and in that case no additional message gets generated.
- Message moderation doesn't seem to make a difference, at least the "Moderate First Topic Message" vs Unmoderated.
- I can reproduce this in the above (premium) group but I cannot reproduce it in a free test group or another premium group, locking a topic there behaves normally.  I didn't test any more groups.

I tried the usual clear & restart browser, different browser, different PC, log out & back-in, didn't help.  I did upload a few PDFs and created a generic link (to a group topic) in Files in this group but that shouldn't make any difference.

I left for now those newly-created stray topics in that group for your examination.
