A virtual reality program could be run and the data saved to disk at
one second intervals. On the second run, the saved data could be
loaded out of sequence. How would the observers in the program know if
they were being implemented in sequence or out of sequence? How would
they know if their second of consciousness was generated with saved
data or with random data that just happened to be the same as the
saved data?

Of course in any experiment we might actually carry out with a human
subject in the foreseeable future there would be noticeable gaps in
consciousness, due to technical factors. What about the virtual
reality experiment above?
