I have had this problem happen for many months. Some items would appear in closed listings right away, while other listings at random times would not appear.
I hope the "fix" really does work.
It is really time consuming to compare closed listings in Auctiva, to the closed listings in eBay. I can't wait for the closed listings to eventually show up (or wait for reconcilation by Auctiva) for 2 reasons:
1. There might be a promotion that is ending on eBay. OR
2. I end most of my auctions on Sun so I have to get them relisted ASAP.
It is much faster to bulk relist in Auctiva, however then I have to manually relist through eBay the listings that are missing.
