If your guild leader has gone inactive, and your guild needs a new leadership, there are a few options.
• Consider connecting with your guild leader on social media or through his/her friend to see whether you can get in touch with him/her. If you can get touched with the leader, you can let him/her know that the guild needs help.
• Wait for 1 month - if a Guild leader becomes inactive for 1 month, the Guild leadership will be automatically transferred to an active co-leader. 

To all Guild leaders: 
To maintain your leadership and prevent it being automatically transferred to a co-leader, please stay active and sign into the game at least once every 30 days! Once the leadership is auto-transferred to another player, the change is final. Our support staff will not be able to get your leadership back!
