Buggy source:

Fixed version (ground truth):

      Game.getInstance().getBoard().setData((List<Map>)obj);
    }
 else     if (command.equals("String_Node_Str")) {
      Game.getInstance().setPlayers((Map<String,Map>)obj);
    }
 else     if (command.equals("String_Node_Str")) {
      int player_id=this.convertToInt(((List)obj).get(0));
      int x=this.convertToInt(((List)obj).get(1));
