1.3.21 Standard Registration throwing big error!

If someone tries to create an account on my site with the standard quick registration they are getting hit with this ugly error......

TABLE '(my db).JOS_SOCIAL_PRIVACY' DOESN'T EXIST SQL=INSERT INTO `CA1_SOCIAL_PRIVACY_ITEMS` (`PRIVACY_ID`, `USER_ID`, `UID`, `TYPE`, `VALUE`) SELECT `D`.`ID` AS `PRIVACY_ID`, '3689' AS `USER_ID`, `A`.`ID` AS `UID`, `D`.`TYPE`, `D`.`VALUE` FROM `CA1_SOCIAL_FIELDS` AS `A` LEFT JOIN `CA1_SOCIAL_FIELDS_STEPS` AS `B` ON `B`.`ID` = `A`.`STEP_ID` LEFT JOIN `CA1_SOCIAL_APPS` AS `C` ON `C`.`ID` = `A`.`APP_ID` LEFT JOIN (SELECT PI.`ID`, PI.TYPE, PI.RULE, IFNULL(PIM.`VALUE`, PI.VALUE) AS `VALUE` FROM JOS_SOCIAL_PRIVACY AS PI LEFT JOIN JOS_SOCIAL_PRIVACY_MAP AS PIM ON PI.`ID` = PIM.`PRIVACY_ID` AND PIM.`UTYPE` = 'PROFILES' AND PIM.`UID` = '1' WHERE PI.`TYPE` = 'FIELD') AS `D` ON `D`.`RULE` = `C`.`ELEMENT` WHERE `D`.`TYPE` = 'FIELD' AND `B`.`TYPE` = 'PROFILES' AND `B`.`UID` = '1' AND `A`.`ID` NOT IN (SELECT `E`.`UID` FROM `CA1_SOCIAL_PRIVACY_ITEMS` AS `E` WHERE `E`.`TYPE` = 'FIELD' AND `E`.`USER_ID` = '3689')

Any ideas on the cause / fix for this!
