Adding a point, then refreshing the mesh results in wrong mesh for one frame

[Jellybit]

I've attached a project where every second, I add a point to the curve, then refresh the mesh. When I do this, for a single frame, the mesh crisscrosses itself only in the latest segment, then corrects itself the next frame as shown here:



I thought a first that it was because the points were too close to each other, but it should be past the previous point, and should render correctly even if it's close. Also, I set the curve to "linear" to make sure it wasn't this point proximity problem, and the issue still occurs. This bug is making it so I can't draw the path of a curve gracefully.
