Your first post says:
Why the guild is BUG.
Bug reports goes to the Bug section.
But I think this might be a minor glitch. If it occurs to everyone ofcourse.
If you lost your guild like this:
You were making a guildwar/duel.
You get D/C'd in the middle of the guildwar/duel,
then you come to report.
