Incorrect CZML-Corridor behavior

[leylines]

What happened?

I am working on a project in which I create czml from a PostGIS database. I create polylines and corridors with the exact same coordinates. These consist of a start and end point, as well as a middle point.

Now it so happens that the corridors sometimes deviate very strongly from the (correct) polylines. However, this only happens with certain corridors; there are corridors that are exactly correct.

In the Sandcastle example, there is one corridor that is exactly correct (Aleisa 5) and one that deviates greatly (Aleisa 6).

I have opened a corresponding thread in the forum, which I would like to refer to.

Thank you for looking into this, it is very important to me that the representation of the corridors matches the polylines.
