This collection is stuck at 7/9 for me. I have completed both the Griffonrook Run and Craze's Folly jumping puzzles but neither have awarded the related feasibility report. I have submitted bug reports with screenshots through the game.
As it stands I am unable to progress this collection. All of the other reports were awarded fine and most were done on the same day as these two.
If anyone else has had similar experience, and knows a way to get the items awarded then please share.
