Hi all
I am making an airport I have put track direction markers on invisible track but the plane just ignore them.

Just found out its new track markers any were I put them( trains planes} ignore them.
Loaded a save of the same route a month ago put some on that and they follow them ok.
Must be something I have done to the route in the last weeks.
A bug or something
