The main problem was when we uploaded some auctions a while ago which unknowingly didn't have some fields filled out correctly, caused some problems with combining auctions. It also caused some auctions to start again after they had closed successfully. We still have some of the early auctions causing these problems left, but they will diminish with time.
Last week one day we were down due to an update which caused problems. That should not happen again, but if it does we know how to fix it now.
If you see anything happen on this site that doesn't look right please let us know as soon as you can.
