Well, when I checked in around 10:30pm on the 5th, three threads didn't show all of their posts the first time around. I wouldn't've noticed, except that as I was trying to post in one of them, I scrolled down and saw two posts that hadn't showed up when I read through it, so I went back over all of the other threads and found two others that had 'skipped' posts. The problem doesn't seem to've recurred.
