Script Stopped Working - Walking on Walls

did you update unity? that can cause a problem. post your codes you think are interfering.

I found where the bug is, but I still can't fix it.

 function JumpToWall(point: Vector3, normal: Vector3){
     // jump to wall 
     jumping = true; // signal it's jumping to wall
     rigidbody.is$$anonymous$$inematic = true; // disable physics while jumping
     var orgPos = transform.position;
     var orgRot = transform.rotation;
     var dstPos = point + normal * (distGround + 0.5); // will jump to 0.5 above wall
     var myForward = Vector3.Cross(transform.right, normal);
     var dstRot = Quaternion.LookRotation(myForward, normal);
     for (var t: float = 0.0; t < 1.0; ){
         t += Time.deltaTime;
         transform.position = Vector3.Lerp(orgPos, dstPos, t);
         transform.rotation = Quaternion.Slerp(orgRot, dstRot, t);
     //   Debug.Log(t); 
        yield; // return here next frame
     }
     myNormal = normal; // update myNormal
     rigidbody.is$$anonymous$$inematic = false; // enable physics
     jumping = false; // jumping to wall finished
 }

The bug is when transform.rotation gets from the orgRot to the dstRot. When it happens, my character gets back to original rotation and sticks to the wall.
