TIPS

   - before removing entity be sure the components data arrays or maps are cleared
     example 1 solution:
     
         entity.removeAll();  // before using removeAll() check if the components data has arrays or maps
         SpriteComponent sprite = Mapper.sprite.get(entity);
         sprite.clear(); // to avoid leaving traces of unneccesary texture traces
         entity.remove(SpriteComponents.class); 
         
         SpriteComponent implements Component {
            public Array<Sprite sprite;
         }
      
      example 2 solution
      
         SpriteComponent implements Componenet, Poolable {
            @Override
            public void reset() {
               // clear your arrays, maps or data
            }
         }
