I'm playing State of Decay 2 on Xbox One. I have a "Sheriff" leader. BEFORE clearing out all the Plague Hearts, a "Sheriff:" mission popped up, but I didn't immediately address it, not knowing what it was. As of this morning, all the plague hearts have been destroyed. Characters have commented on it (one of them saying "Is this seriously the last one?" before we destroyed it, and then saying something celebratory afterward). But there's no indication what to do next. Standard missions keep popping up, but no further Sheriff missions. Is there something I have to do to trigger the end game? I've continued playing for about an hour, completing other standard missions, but there's no indication that any end game is forthcoming. Anyone else having this problem?
