I am trying to pierce the end point of a spline to the edge of a circular surface. When I select the end point of the spline, and the edge that I want the spline to pierce, the end point appears to pierce it just fine. But when I close the sketch, the end point jumps all the way across the model to the opposite side and pierces there instead. It actually extends the spline, dragging it across the model.

Has anyone else experienced such a wierd quirk like this?
