You need to do something to give players a way to resolve delinquent or bad players. When a clan lead stops playing for more than 14, 30 days an active player should be able to take on the role in the very least in a temporary capacity. If a player is inactive in a dungeon for longer than 15 minutes the other should be allowed to leave with their investment or start a new one. Fix it. Stop letting bad players waste the investment of others
