The Drax Cave/Bug in "Forum Activity" module

A bug has recently crept into the "Forum Activity" module. That's the thing just to the right of this message, there under the search bar.

It used to be — and I assume this is still the intended behaviour — that a thread was only cycled into "Forum Activity" when a new message was added to the thread. Now, however, threads are getting placed into "Forum Activity" when admin make simple administrative changes to the thread, or when people edit pre-existing posts. This means that all of a sudden bot edits are moving really old threads into forum activity, or the simple act of closing a thread ironically puts a thread into Forum Activity — so that more people can see that they cannot contribute to it.

A bug report has been filed with Wikia. Until then, expect for active conversations to get buried by old ones.
