Puzzle Hunts are Everywhere, albeit one less place

Corby sent me mail yesterday: some of the environmental data for the 2-Tone Game went away. I was already planning to take today as a vacation day, so now I had a morning activity. Confirm that the data was gone (yep) and then tweak that puzzle to work around. Things change, cities change. But the the 2-Tone Game adapts and survives. And now players won't have to walk as far.
