"Cure Lost" Mission from Montague bugs in flashback

[Yomo Kimyata]

I thought I would kill two birds with one stone by filling the "Cure Lost" mission while using the Ouro to go back and run Penny's arc.  To my surprise, when I completed the flashback, my Cure Lost counter is cured 21 of 20, but the mission is hung.  Montague only offers the opportunity to abandon the mission.

Same here, when I used the wand in an Architect story. It disappeared despite having charges left, the mission failing to complete.
