The messages and bars on the Where's My Refund webpage change all of the time; and sometimes the same message is displayed continuously, or the bars disappear entirely (they may return later). The disappearance of the bars, as a stand-alone action, signifies nothing important at all.
While we at TurboTax have no way of finding out specific information about the processing of an individual tax return once it's been transmitted to the government, the activity you observe on the IRS's "Where’s My Federal Refund?" website sounds normal. The behavior that you observe is more likely an indicator that your tax return (and refund) is simply moving through the processing system.
