Today I've noticed a number cases when clicking to go to the precious or next thread in a forum leads to a nonsensical result in that it isn't the precious or next thread, even when sticky threads are taken into account and the situation cannot be explained by very recent posts affecting the new to old ordering of threads. For example, I can be reading a post from a few minutes ago, click to go to the previous or next thread in the forum, and FT takes me to some other thread where the latest post is several hours old. I noticed this on the DL forum persistently (but not consistently in that a few times FT got it right) over at least the last several hours.
