why was I kicked from my own club?

[VacantVisage]

I logged in to find a message saying I was kicked from my own club. I was literally the founder of the club, so it should have been impossible for anyone else to kick me. I've logged out and back in again, and still I'm not back in. my friend is the new owner, and I'm sure I could just contact him and have him add me back, but how do I become the club owner again?
