I have a similar phenomena to report. I have only made the one post on this thread, but when I composed it there was only one reply post visible (Zoony's), yet now I come back to the thread there are 8 posts that I haven't seen before mine which takes it a bit out of context as a reply (since it refers to post #1 by UP) and other comments move away from my point. I wonder what happened?
