and fuction
function find_distance_coords(&$pointarray,$distance)
{
// We find the nearest lower point for each distance,
// then linearly interpolate to get a more accurate point
// this saves having quite so many points-per-curve

$index=find_distance($pointarray, $distance);

$ratio=($distance - $pointarray[$index][2]) / ($pointarray[$index + 1][2] - $pointarray[$index][2]);
$x = $pointarray[$index][0] + $ratio * ($pointarray[$index + 1][0] - $pointarray[$index][0]);

Do you still have this issue?

What does your map config look like? This would probably be caused by having a link between two nodes at the same position, or something like that.
