[Aquarian Sports Cards]

Because a live auction doesn't just cut off bidding at a given time, it runs until there is no bidding on an item. Extended bidding is the way to most closely mimic that without an auction taking several days to end, as it would if you closed thousands of lots in order waiting until you had no bids on a given lot to move on to the next one.

Also if you think there's problems now just wait until you see the server crashes with a fixed time ending. literally EVERYONE will be trying to jam last second snipes down the server's throat. It would be a disaster of epic proportions.
