Moderation: Reported posters get kicked to unaccessible page

WP MS 3.3.1
Moderation 1.0.7

If you report a user and then they log in, it redirects them to /wp-admin/admin.php?page=moderation-warning after about 2 seconds, which I assume is to show them the warning. The only problem is it says they don't have access to this page. The user I have tested with is an administrator.

Cheers,
