A few days ago we been having a certain person break into the server, and somehow made himself the highest admin rank possible, Hes been destroying other´s stuff and being an idiot. Our server´s admins themselves havent found a way to ban him.

He also makes himself invisible, and always speaks through the console.

Is There any way to get a list of all the players so we can find his player name and kick him and ban him? and of course, de power his rank?

Thank You
