Android joystick doesn't work after 2nd level >.>

So I just made this script for android joystick, works perfectly tested and approved on my phone. But there is one thing though -- The joystick magically stops working after 2nd level, even though I never changed a single thing. To make sure I haven't changed anything, I made another script, the same as the previous one. Still doesn't work ._. Weirdest thing is that it won't even move when I make a script that would literally only move the joystick when I click on it. Is something altering it in my scene or is it just aliens? Can someone please help me with this it's driving me crazy >.< Here's the script if it helps at all
private Image bgImg; private Image joystickImg; private Vector3 inputVector;

 private void Start()
 {
     bgImg = GetComponent<Image>();
     joystickImg = transform.GetChild(0).GetComponent<Image>();
 }

 public virtual void OnPointerDown(PointerEventData ped)
 {
     OnDrag(ped);
 }
 public virtual void OnPointerUp(PointerEventData ped)
 {
     inputVector = Vector3.zero;
     joystickImg.rectTransform.anchoredPosition = Vector3.zero;
 }
 public virtual void OnDrag(PointerEventData ped)
 {
     Vector2 pos;
     if (RectTransformUtility.ScreenPointToLocalPointInRectangle(bgImg.rectTransform
         , ped.position
         , ped.pressEventCamera
         , out pos))
     {
         pos.x = (pos.x / bgImg.rectTransform.sizeDelta.x);
         pos.y = (pos.y / bgImg.rectTransform.sizeDelta.y);

         inputVector = new Vector3(pos.x * 2 + 1, 0, pos.y * 2 - 1);
         inputVector = (inputVector.magnitude > 1.0f) ? inputVector.normalized : inputVector;

         // Move Joystick IMG
         joystickImg.rectTransform.anchoredPosition = new Vector3(inputVector.x * (bgImg.rectTransform.sizeDelta.x / 2) , inputVector.z * (bgImg.rectTransform.sizeDelta.y / 2));
     }
 }
 public float Horizontal()
 {
     if (inputVector.x != 0)
         return inputVector.x;
     else
         return Input.GetAxis("Horizontal");
 }
 public float Vertical()
 {
     if (inputVector.x != 0)
         return inputVector.z;
     else
         return Input.GetAxis("Vertical");
 }
