Besides a post from me just disappeared (and you did not do that 😉 ), I saw a post in the ProOrder board disappearing before I could read it. If you now look at that board, the last post is from 4 days ago (Vinnie) while clicking that “4 days ago” link, leads to a new post from Khaled (which is just visible as last post when visiting that board).
And under that last changed topic with a last post in there from Khaled (see below) was at least one more topic I did not read myself and which now is not there. Otherwise I can wonder whether the previous last post in the ProOrder board was a day ago.
No worries about my own vanished post – I already reposted that.
