Site and Category disappeared?

Our site was originally listed for a very long time within the category Regional/North_America/United_States/California/Business_and_Economy/Real_Estate/Mortgages

The category seems to have disappeared, and I can't find the site. Should we resubmit?

You didnt tell us what your site was, but I would guess the category was merged with http://dmoz.org/Business/Financial_Services/Mortgages/United_States/California/ which seems to cover pretty much the same. Maybe you could have a look there.
