The agent goes back and forth after calculating the path with
seeker.StartPath (transform.position,target.transform.position, OnPathComplete);. The gizmo shows the correct path. Please watch this short video to get an impression on what happens.
It starts after adding about 100 obstacles during runtime. Is this a known bug or am I doing something wrong? My test case is really simple. I can provide the project if necessary.
