This can happen in rare circumstances based on when the AFT process happens to run overnight. Part of the routine to determine whether a new payment should be calculated is based on a comparison between the last disbursement date and the actual date (to determine if the disbursement happened today). This particular routine reads the system (calendar) date, not the business (activity or processing) date. If the business date hasn't changed yet but it's after midnight local time, when the program runs this comparison it looks as though that disbursement happened yesterday, and therefore doesn't warrant a payment recalculation.

To date this occurs extremely rarely and therefore we have elected not to adjust the coding to accommodate this scenario. We will reconsider this decision down the road if it becomes a more common occurrence.
