Flight Aware Base Layers

Airline flying over the holiday and I always track my flights. That’s enough about that. But looking at FA and loading the filed routes into ForeFlight and then comparing them to the route history I noticed that the Lake Henry VOR in PA is still depicted on the Low IFR chart. Which leads me to believe that the charts used for the Base Layer is obsolete (Lake Henry VOR has been inop for a few years now). No big deal at all, just something I noticed. How often/how long has it been since these charts were updated? Just wondering.

I would venture to say they have not been updated since they were loaded.
