Thanks for looking, and making the fix. And once again for the great tool!

I found what might be a bug. When I enter an east-to-west plan, starting at Rock_Harbor_Dock, I can go:
Rock_Harbor_Dock
Rock_Harbor_Campground
Suzys_Cave
Tobin_Harbor_Suzys_Cave_Junction
Tobin_Harbor_Mount_Franklin_Junction

But coming from the other direction I can't get farther than Suzys ...

This is incredibly useful! Thank you Ingo!
