Mailed returns are taking months to be opened and entered into the system and mailing it to the wrong address will just add a few days more to the process ... this always happens when the IRS changes where they want items mailed to so forwarding them to the correct office is a common occurrence. They just recently announced the actual closing of most of the Fresno office by the end of the year so don't worry about it. Check the IRS site once a week until you see it being processed then a couple of times a week to see when it is approved.
