docs: Reloads and recolorizes our object tile. It is not intended for the actual object tile used
  by a scene object to change in its lifetime, only attributes of that object like its
  colorizations. So don't do anything crazy like change our {@link ObjectInfo}'s
  <code>tileId</code> and call this method or things might break.
