Gizmo error

Hi,

Is this a bug? I have the below code and every time I move around in the scene view I get the error ArgumentOutOfRangeException: Argument is out of range continuously until I move the pointer out of the scene view .. Didn't seem to have it before ..

The line is 19

Unity 5.5.0b7

Code (JavaScript):

1. function OnDrawGizmos ()
2. {
3.     if(spawnPoints.Count > 0);
4.     {
5.         for (var i=1; i < spawnPoints.Count; i++)
6.         {
7.             var path = new UnityEngine.AI.NavMeshPath();
8.             UnityEngine.AI.NavMesh.CalculatePath (spawnPoints[i-1], spawnPoints[i], UnityEngine.AI.NavMesh.AllAreas, path);
9.      
10.             Gizmos.color = pathColours[i-1];
11.             Gizmos.DrawRay (spawnPoints[i-1], (Vector3.up*20));
12.  
13.             var offset = 0.2f * Vector3.up;
14.             for (var ii = 1; ii < path.corners.Length; ii++)
15.                 Gizmos.DrawLine (path.corners[ii-1] + offset, path.corners[ii] + offset);
16.         }
17.         if(spawnPoints.Count > 0);
18.         {
19.             Gizmos.color = pathColours[spawnPoints.Count-1];
20.             Gizmos.DrawRay (spawnPoints[spawnPoints.Count-1], (Vector3.up*20));
21.         }
22.     }
23. }

EDIT..

Sorry my fault don't think I should have been using Gizmos, changed to Debug.DrawLine and all working fine now, Mod's please feel free to delete this post if it's not a bug, thanks.
