Cakephp delete all relationship's cache

When i use this line: 

 $this->User->saveField('last_activity', date('Y-m-d H:i:s', time()));

CakePHP delete all cache of model relation with User. ( Almost all model relate with User) .

I must use Configure::write('Cache.check', false); prevent Cakephp clear all .

Is this normal in cakePHP ?
