BFU's AN-28 appeared in the library today, but not on the front page "what's new". hint ;-)

I know they recently added another category and sometime during this change, there was a small problem that caused them to need to regenerate the list. That upload may have just been lossed in the shuffle, definitely not intentional. And since this list is somewhat automatic, the next list will be generated for the newest uploads. But you have mentioned it here for more to see. :-)
