Duplicate Lots of users were rendered unable to browse the site (no perms)

[Rigel Kentaurus]

I deleted a group (through the admincp)
I had a bunch of users with that as their primary usergroup
Users cannot browse the forum anymore

That's really this bug: http://xenforo.com/community/threads/deleting-specific-usergroup-leads-to-timeout.10599/

If you UPDATE xf_user SET user_group_id = 2 WHERE user_group_id = X;

And then rebuild user caches, it should be ok.

Seems like it is a problem for sites with larger memberships.
