ATF - 90 days and counting, still have not cashed my check

[Sticks]

Problem being my check is a Certified Bank Check - expired on 4/17 (do not cash after 90 days). Bank calls it a "Stale Check" after 180, and won't refund for 2 years if not cashed. Otherwise I have to do a stop payment and fee.

Planned obsolescence by the ATF? - Here is to hoping that the FFL finds it.
