How do I gain control of a clan when the Warlord is inactive? No one in the clan can kick/accept members. No one can run epics.
You would have to forward a request directly to the Apes.. As far as I know there is no other method of gaining ownership of any clan...
Press the ape icon on the bottom left of the app home screen. That will allow you to start a conversation with the Devs... But I wouldn't be expecting too much, would probably be easier just to start a new clan if I'm honest.
