Not sure the source of this but we updated our Wowroster from 1.7.1->1.7.2 and also used GuildProfiler v2.0.3.
What resulted when things were returned was a mess, specifically in the guild_rank/guild_title column. The guild_titles were actually the guild_ranks. And the guild_ranks look like they didn't update at all from last time (as we had some members move from one level to another and I can still see in the db the old guild_rank # in guild_rank).
Did I do something wrong in my upgrade or is there some compatibility issue with the new GuildProfiler? I followed the instructions for using the upgrade.php, replaced all files in the main directory, etc etc.
