I just finished the quest The Archive and like to share a couple of observations that might or might not be bugs. Other things that happened are not covered by the rules, I think. Beware, some spoilers ahead!
1. I freed the Ironbound before killing the other monsters in the secret room tile (changelings). When I was washed to the next set of tiles, the changelings where still on the monster tracker but the app gave no indication where they should be placed. Also, I did not see where The Archive should be placed. Did I just miss it?
2. To my big surprise in the middle of this quest transition to Act 2 took place! As usual, I was told to put Act I monster cards back to into the box and use Act II version from now on. Are monster cards in play (Mirklace in my case) immediately replaced? What about The Archive? Is his Monster card replaced, too? What happens to damage tokens on his card?
3. Can the Archive use his Protect ability on heroes?
4. After the transition to Act II suddenly The Archive activated as a usual monster, instructing me to attack heroes. See this screenshot. A bug?
