When a user is deleted, the appraisals that were completed by their manager are still listed on the manager's page. When one of the appraisals is clicked, an Invalid User error is generated. Would it be possible for either the appraisal to remain visible, or to be removed from the manager's (and one presumes manager's manager's and appraiser's) page? Either way, it should still remain in the Appraisal Status report source and any other appraisal report sources so that details can still be retrieved.
