Comment: Mistake in the migration process. During the migration process, the last updated timestamp on the topics were set to the last updated timestamp of the topic itself rather than the last comment. Hence the ordering of old topics are a bit off. It will be fixed soon. New forum topics are not affected BTW. In fact, if you update an old topic with a new comment, it should move to the top of the list. → Mistake in the migration process.
