Buggy source:
private void update(){
  if (session.getEquipment(pieceIndex) != null) {
    boolean addButtonExists=false;
    for (int i=0; i < decorationNames.length; i++) {
      decorationIcons[i].setImageDrawable(fetchDecorationIcon(pieceIndex,i));
      if (session.decorationIsReal(pieceIndex,i)) {

Fixed version (ground truth):
private void update(){
  if (session.getEquipment(pieceIndex) != null) {
    boolean addButtonExists=false;
    for (int i=0; i < decorationNames.length; i++) {
      decorationIcons[i].setImageDrawable(fetchDecorationIcon(pieceIndex,i));
      if (session.decorationIsReal(pieceIndex,i)) {
        decorationNames[i].setText(session.getDecoration(pieceIndex,i).getName());
        decorationNames[i].setTextColor(getResources().getColor(R.color.text_color));
        decorationMenuButtons[i].setImageDrawable(getResources().getDrawable(R.drawable.ic_remove));
      }
 else {
        if (session.decorationIsDummy(pieceIndex,i)) {
          decorationNames[i].setText(session.findRealDecorationOfDummy(pieceIndex,i).getName());
          decorationMenuButtons[i].setImageDrawable(null);
        }
 else         if (session.getEquipment(pieceIndex).getNumSlots() > i) {
          decorationNames[i].setText(R.string.asb_empty_slot);
          if (!addButtonExists) {
            decorationMenuButtons[i].setImageDrawable(getResources().getDrawable(R.drawable.ic_add));
            addButtonExists=true;
          }
 else {
            decorationMenuButtons[i].setImageDrawable(null);
          }
        }
 else {
          decorationNames[i].setText(R.string.asb_no_slot);
          decorationMenuButtons[i].setImageDrawable(null);
        }
        decorationNames[i].setTextColor(getResources().getColor(R.color.text_color_secondary));
      }
    }
  }
 else {
    for (int i=0; i < decorationNames.length; i++) {
