Cambiar a un nuevo estado plano requiere eliminar la referencia de todas las superficies retenidas. En el trabajo requerido para los cursores de mob, las superficies mapeadas comenzaron a almacenarse en cach\u00e9, pero la variable que indica si la superficie est\u00e1 actualmente mapeada no se restableci\u00f3. Esto provoca fallos ya que el estado duplicado, incorrectamente, indica que esa superficie est\u00e1 mapeada incluso cuando no hay ninguna superficie presente. Esto se debe a que despu\u00e9s de eliminar la referencia a la superficie, es perfectamente posible que el avi\u00f3n est\u00e9 respaldado por un bo en lugar de una superficie. Restablezca el indicador de superficie asignada al eliminar la referencia a la superficie del estado del plano para corregir las desreferencias nulas en la limpieza.
