Game Mechanics: Guild leader bug?

[unim21]

A member who joined our guild recently is suddenly being listed as the guild leader when he types /guildstatus. He cannot remove himself from the guild, nor as guild leader can I remove him since I get the "must be lesser rank than you" error.

I'm still listed as the guild leader as well. When performing the /guildleader command on myself, it's successful. When the member in question types the same command he gets an error saying he isn't the guild leader, even though a /guildstatus tells him that he is. He is also able to modify the guild motd.

Has anyone else encountered this issue?
