you should see the question sign if a download has failed.
check in tasks menu->task manager, the error pane what are the errors.
it might be yenc checksum error, bad message-id (with 3.8 you can even download such an article to see what is inside), etc.
it cannot just ignore tasks, if downloads succeed - you see the body icon, if not - the question sign
i've just downloaded the article you mentioned, no problem at all, zip opened ok, also there is no sign of the sporge attack against this particular post (used xpat search group to locate it).

check the error pane, i guess you'll see something there.
