A Sacred Place from Father Hawthorne in Kingsmouth can become unfinishable without pausing and picking it back up.
Steps to reproduce:
- Get two people (ungrouped) with the mission.
- One person starts slightly ahead of the other person
- Person B activates the final ward while Person A is already fighting the hulk.
- Person B is given the task to kill the Vengeful Hulk
- Person A kills the hulk before Person B can attack it
- Person A finishes mission, Person B is stuck at “Kill Vengeful Hulk” with no hulk to kill
At this point you can pause and pick the mission back up and the hulk will respawn.
