Dear Devs,
It was extremely inconsiderate of you to go about replacing the AH with the shiny new Shard Exchange and, at the same time, try to give the AH some long boring lecture on math. How could you possibly think the AH would be even remotely interested in something so mundane when you had hurt it so deeply?
I suggest you take it out for some ice cream, let it know that it's still important and that the Shard Exchange is NOT here to replace it, but just take some of the load off... Perhaps you could put in the extra effort to show it how much it means to you... Then you can give it the math lesson again, confident that you'll be receiving its full attention.
From the release notes: The Auction House has been given a math lesson and will no longer tell you that your bid amount was too small when you were bidding what it told you to.
From the AH this morning: (Error): The bid you are trying to make is too small.
