Defend and join banners are all sorts of screwed up after the forced update that added the new mythics to the den and castle. People are unable to reliably defend war runs and entire waves have gone through undefended because of this.
@PGGalileo in game forced updates aren’t supposed to interfere with the banners. That’s why when major updates happen everything is turned off (atlas PvP, castle shields up, wars blocked). So what’s going on?
