Well it is only a guess but based on the difficulties from the last two days I have experienced, I would say eBay is having technical difficulties. The End of Auction emails as well as Listing confirmations have been extremely slow. Auction information is not being released as it should be often taking up to 30 minutes as opposed to just a couple of minutes.
The manual update doesn't require any information release by eBay as it is for just a single auction lot. So when you update just that one auction lot, then eBay returns the info for just the one thing AW2000 requested.
