This is not a bug in any way sorry. A default vbulletin install does indeed have a field2 which is the location field in the userfield table. yes you can as a vb
admin delete any field you wish however our application and its queries are coded to a default vbulletin install. should you wish to remove a field you are free to modify the get_profiledata field in the vb3.php to suit your modified needs.
