If the township leader hasn't been playing the game for too long, leader's role can be transferred to the most active player in the township.
Players who are in the township with an inactive leader will have a chance to get a special letter to their in-game mailbox that will offer them to compete for the leader's position in a special festival. The player who earns the highest score in the festival will become a new township leader.The notification about changing the leader will arrive via game mail beforehand.
Such letters are sent out rarely, but if you are playing in the township with an inactive leader and haven't received such a letter yet, don't feel upset. Your township may have a chance to get it next time.
However, if the letter doesn't come for a long time and the leader is still inactive, we recommend you leave the township and join another one or create your own one.
