Forum Home last post user account link glitch

Hello,

If I view the forum "home" (where it lists all the various subforums), under the "Last Post Info" column it lists the thread name, and under that "by" and a link to a user profile.  For instance, at the moment, it shows "Elemental: Making a Quest part 2" with Frogboy listed as the last poster.  However, if I click on "Frogboy" there, I get Anthony_Christianson's profile instead of Frogboy's for some reason.  I presume this is some sort of glitch?

Thanks.
