Feedburner not showing updated post ?

I’ve been wondering how come Feedburner doesn't show the latest post on my feed list. But unlike many other people who’s experiencing not updated post for a long time (you can try searching the web for it). In my case the latest post is not going to be displayed even one days after i posted it unless i post something new

I thought it was something related to wordpress problem or cache problem, but after double / triple check it, i can see the latest post from feed without problem (i do this simply by changing my user agent into Feedburner user agent because every request made into my site feed which is not came from Feedburner user agent simply will go into my feedburner address)

Hm … i dont know if this is a temporary problem or not (because i don't really track this site feed usage), but if this problem still continue to occur i might remove my feedburner address and use the original feed .. but we’ll see about that later ;-)
