There is currently a bug where sometimes a guild can be created twice with the same name and server. I have been unable to track down this bug so far, but I am making a change to the database structure that will prevent entries with duplicate names from occurring. This means when the bug does occur in the future, users should see an exception message, and this may help me figure out what is causing it.
If you are one of the guilds affected by this bug, I resolved duplicates using the following automated code:
(1) If one of the guilds in the set had no reports, I deleted that guild.
(2) If both guilds had reports (which means the members of the guild messed up and uploaded to both for some reason), I renamed the old guild by adding the suffix “Buggy Duplicate” to the end.
If you are affected by this change in a negative way, i.e., the guild marked as the Buggy Duplicate is actually the real one, let me know, and I can invert the naming. One of them has to be marked with a bogus name though… you don’t get to use both.
