Happened twice in the following thread:
Similar thing happened earlier today in the Intimidator Pic Thread (yet the post has been deleted).
I've also noticed a few other unusual occurences:
1. Sometimes "edited" posts won't reflect the changes I've made to them.
2. Various marker index pages will indicate that replies have been made to a thread, but will only show the first post (sometimes first two posts).
3. This one's a little less significant. When I recently moved a thread from the Timmy Forum to Air Systems, the Timmy index page did not say "Moved:" beside the thread title. However, when the thread was clicked, I was taken to the thread (properly located in Air Systems).
4. Lastly, as you know, sections of various users' posts have been repeated within a reply. Quite a common occurence lately.
P.S. #1 has been most common for me. In fact, this entire reply did not show up after I posted it. I had to re-paste the response.
