All Track Lost On Self-build Routes

Since the update I have lost all of the track on self-build routes - everything else is still there, just no track!!

What's going on? I certainly can't find a way of getting the track back!

 

Don't panic.

Please post your tracks.bin (Content\Routes\YourRouteGUID\Networks\tracks.bin) here (just attach it zipped) and we'll figure it out.

 

Does the track still appear on the map or is it fully gone?
