I was in an Expedition, the map Cinder Peak, playing as Mercenary Kruber. Near the beginning of the level in a lava peninsula I got stuck on a small pit and could not escape. My teammates killed me to revive me, but I could still not get up. They had to rescue me later on in the level (which also was very far away.)
Picture is of the pit.
