People random getting timeout for 26+days.

So sinds this evening connected people getting timed out for 26 days whitout anyone pushing a button. There is also nothing about it in the server log. And no one has rights to do timeouts beside me and can only do 14 days. There are no bots on the discord that can do so. And there seems to be no way for me to take the timeout off. They can still join other servers. How or why is this happening? And what to do about it.
