  <p>Can anyone explain to me what's going on and how I might find what exactly is causing the crash? </p>
  
  <p>There are two places in my code where it crashes, but it's fairly random when it does. After executing this method:</p>
  
  <pre><code>private void destroyFiller(){ //Deletes filler
          if(filler[fillerNum].active){
              Log.e("destroyFiller","Destroying filler");
              filler[fillerNum].active=false;
              filler[fillerNum].body.setActive(false);
              scene.detachChild(filler[fillerNum].sprite);
              fillerCount--;
              fillersLeftText.setText("Balls left: "+Integer.toString(fillerCount));
  
              if(fillerCount==0)
                  gameOver();
              Log.e("destroyFiller","Destroyed");
          }
      }

  <p>And after executing the indicated line in this method:</p>
