What Was the Most Tragic Policy Development of 2012?

I had an interesting run-in this past month. Wjile in the process of buying a house, the title company I was dealing with was told by the IRS that I had not filed a return for 2010, qand wanted to know why. When I visited the local IRS office, I was told that there was a record of my having filed, and it was closed. I had taken a copy of my 2010 return with me; it was the stamped as having been received and I was given a copy of it with the stamp on it, to be given to the title company..
