I use it every day and it was fine until last night. Right now if I go to find my own posts, it only shows 993 posts, whereas I have ~1700. Most alarmingly, my posts since Oct 24 until last night are not showing up at all (I had several). However, if I go to the thread where I made those posts, they are still there. So it's just not showing up in the find posts by user feature.

Example: this post of mine on Nov 3.
