Guild Leaders Can Hand The Guild Over
If you founded a guild, you were stuck with it. Leaving was refused outright for a leader, and the message you got told you to transfer leadership first, which was advice for a feature that did not exist. That was a genuine dead end: the only way out was to ask us.
Every member row on your guild's Members roster now carries a Make Leader control. Pick a member, confirm, and they take over as leader while you step down onto the highest rank still open below them. Your own row does not offer the control, because you cannot hand the guild to yourself.
