More json_encode migration

I swear one of these days I'll just do a search and replace all of them

classes/paranoia.class.php

     return false;
   }
   if (!is_array($Paranoia)) {
-    $Paranoia = unserialize($Paranoia);
+    $Paranoia = json_decode($Paranoia, true);
   }
   if (!is_array($Paranoia)) {
     $Paranoia = array();

classes/users.class.php

       } else {
         $UserInfo = G::$DB->next_record(MYSQLI_ASSOC, array('Paranoia', 'Title'));
         $UserInfo['CatchupTime'] = strtotime($UserInfo['CatchupTime']);
-        $UserInfo['Paranoia'] = json_decode($UserInfo['Paranoia'], true);
-        if ($UserInfo['Paranoia'] === false) {
+        if (!is_array($UserInfo['Paranoia'])) {
+          $UserInfo['Paranoia'] = json_decode($UserInfo['Paranoia'], true);
+        }
+        if (!$UserInfo['Paranoia']) {
           $UserInfo['Paranoia'] = array();
         }
         $UserInfo['Class'] = $Classes[$UserInfo['PermissionID']]['Level'];

sections/user/user.php

     $Paranoia = $CustomParanoia;
   }
 } else {
-  $Paranoia = unserialize($Paranoia);
+  $Paranoia = json_decode($Paranoia, true);
   if (!is_array($Paranoia)) {
     $Paranoia = array();
   }
