Could it be that you’ve unpinned it? This forum gives you the power to pin and unpin (generally pinned) topics as you see fit. To the left of the title you should see a pin. If it’s pointing down, the topic is pinned; if it’s pointing up, it’s unpinned. Click on it (or tap on it if on a mobile device) to reverse it.
Also worth noting is that if you scroll all the way to the bottom of the topic it will become unpinned.
