I have a War Plan active and was doing a run on the Pit. I disconnected the game inside the pit and the next time I logged in the War Plan was gone from the quest journal.
Completing a pit run does not progress the war plan and I have no Marks to create a new war plan.
I cannot progress the game.
I actually would need someone from tech support to reset something in my game so I can keep playing.
Update: If you ever run into this, just make a new character and skip campaign.
War plans are available from lvl1, just complete one and you have 3 Marks to reset the ghost War Plan.
If you’re rerolling War Plans trying to find the improbable one that will allow you to complete the “same activity” challenge, just always leave one Mark available to save you an headache.
