After reaching the final encounter of Ketchcrash, players can speed past the activation/rally point before the barrier blocks the door outside. The barrier then appears, locking all players outside and preventing activation of the final fight, softlocking progress and forcing all players to abandon the activity. Failed workaround: We dropped down underneath the platform where the final encounter takes place, to an area earlier in the mission, but a locked door blocked our path and we could not reach the activation point that way.
