It may be mistake or joke

This kind of thing happened couple of times in past two years, each time, the processing dates were changed back to old ones. This time, EB2-1 NIW is also going forward too much, almost half year, it is unbelievable. I know a guy downstair in our building, his NIW case is Feb 2003, but he is still waiting. Vermont may be crazy, at least the computer guy responsible for renewing the processing dates has a problem.
