I have 2 users on the site and on the front end when i click on user brad it takes you to user carlucci profile and not brads profile. Here are the user names and user ids.
brad 823
carlucci 783
If i go to carlucci, it goes to carlucci, if i click on brads, it goes to carluccis profile as well.
It has been long standing issue and probably first began when I migrated from Jomsocial at the end of last year.
