Well done dude, awesome!
I have tested it and it works better:) However when I load up a save and have fast travel state set to "Visited only" it doesn't work. But when you switch it to "Show all" and then back to "Visited only" it works again!
Just thought you might be interested to look into that. Eitherway it is a mod worth having.
P.S. Found that dying and loading a save, resets this problem. Also, some areas that I have visited can't be fastravelled to. If you can manage to fix that "Visited only" state option that would be amazaing!!
