This time, at least a portion of my route has duplicated itself between the route and session layer and attached itself at the spline points... See pictures, I'll try to explain as best I can.
Flying around my route, trying to decide what to work on. I notice that I have a bunch of three-arrowed junctions... I can assure you I should have NO three-way junctions on this route.
I also noticed that the green arrows aren't quite green.... I delete the junction to replace it but to my surprise the junction is still there but now the arrow is properly green.
But what's up with that three-way junction? I delete one of the tracks coming off it, and there's still a junction there (with a green arrow, not two reds as I would expect)... Also what's up with that stub that's left?
Figured out there's two tracks at these spline points still....
Here's another stub with the same problem.
What it doesn't show is that I added a spline point about where my compass is as an experiment.
When I move that added spline, the duplicated spline shows itself. I confirmed that one is in the Session Layer and the other is in the Route layer.
Is my only hope to delete my session and try again? Unfortunately these stupid layers still get me once in a while and I've added some things in route and some in session because I edit the session but sometimes forget to switch to the route layer before actually placing track.
But what would cause this? I didn't lay down my own duplicate track and manage to place the splines exactly perfectly in the exact same spot (causing them to create junctions).
For the record, this is TANE, Build 90945.
