Been trying to finish this goal for ages now and up until 2 weeks ago, I had only managed to give Belladonna 15 out of 20 inscriptions. I am now completely mystified having returned from vacation to see that I can no longer send dark plants and collect inscription by doing so. The adventure has been removed from the Queens Court and the Barracks! This is very frustrating as I can't complete Sister Sister or skip it! Any ideas anyone????
