Whoa whoa whoa there. That be a typographical error. It would be suicidal to the bad guys if I made one of the Lovers make the Baner autobaned. Oz and Cordelia are protected by autobane as intended (not as written, where sadly the text of the rule was written before we juggled a couple of the character names).
Oz died because Oz was vulnerable. This occured because I received no PM indicating his use of "Everybody loves Oz/Oz Loves everybody" which is not a passive (automatic) ability. If it was automatic, it would be too easy for Oz to maintain his pseudoinvulnerability.
