Ok I seem to be having a really bad week when it comes to the New forum

Here’s what is happening now: I cannot see the last several posts I made in several forum sections. When I go to the relevant discussion (eg. Election Odds in 2004 U.S. Presidential Election) I just see the last post nym90 made there and no sign of mine. However my post tally has increased with each one I posted and (get this) they register in the "Last Post" column on the main forum page and not only that, when I click on the link, I see the post at its place in the discussion after nym's post. Can anyone shed any light on this phenomenon??
