the old, not updated ww base, does not influence players ww rank. and your example of classical lvl ww base actually being global age can mean only few things. too fast advancement with a help of crows ( cheating), or just lack of attention to what is going on around lol. one of my alliance member was asked to update his ww base, because he was not participating in a world wars for half year or so, and his ww rank did not changed when he updated his ww base. he was missing about 25 levels from the actual multiplayer base with some key buildings: extra mortar and redoubt, bunker, airstrip, factory.
