My friend and I both had it yesterday while flying into KDCA on the FRDMM1 arrival. I switched to the NUMMY1 and had no problem with that. The FRDMM1 has eighteen waypoints with alt. constraints where the NUMMY1 has only fourteen. Maybe it has something to do with having 15 or more constraints.We were both using the latest AIRAC from Navigraph (1301).
