After closing Scarnetti Manor, I wend to the cathedral.
Worked my way down the deck til I got to the henchman (Longtooth).
Defeated him, banished a blessing to close the location.
Just because I'm stubborn and just *have* to make sure something is *really* broken, I clicked the Shake Down power button again.
Game locked up.
Alt-tab out, restart.
Scarnetti Manor and the Cathedral are open locations again.
Travel to Scarnetti Manor, icon instantly changes to the "closed location" status.
Reroll to get more items.
BYA scenario action plays.
Apparently the troll that was still in the deck when I closed the cathedral is back in play.
Travel back to that location to confirm that it is, in fact, reopened.
