This one seems to be intermittent - but I've only been through the Druid Grove gate fight twice now....
During the fight at the gate, one of the adventurers was killed by the goblins, but he was still standing upright in a ready position, even though he was reading as dead.
Similarly, Kanon up on top of the gate was dead, but still standing.
I guess they're making their saving throws still?
