Uh oh, you've made the same blunder with the Advanced Scouts quest for the new chapter you did with the last, only worse. I took the 'Southern route' through the Fairies tech tree, through the Fairy Manufactories all the way to Pond of Recreation - planning now to go back through the (largely abandoned) upper branch. Now I get a non-declinable quest to research Advanced Scouts, when I have a mere 9 (nine) ("Nein!") techs to go through before I get there.
Seriously?
