Conference Room Bugs

I’'m noticing some strange things with the Conference rooms. If a regular user creates the room they have owner. Verified by the web interface. If they try to bump someone to moderator using the Pandion client, nothing happens. The user stays as a participant. I can increase their rank bia the web interface, and then that user can demote other room mods.

I’'m also noticing that if the room creator sets the room as persistent, it sometimes does not work. Any ideas?
