Aah, I thought briefly about that! Glad I wasn't too far from the mark on the third branch, then.
Reiterating my previous thought: the amount of secrets and hidden things in the game is unbelievable. Very good for different playthroughs, but must be hard to keep track of all these permutations when developing (and it will probably be harder in future, as story and branching points go on).
Won't take any more of your time, thank you for the hints!
