"choice 1" did cause it to manually select the first option. You were being asked if it should choose Vlad, Isabelle or Masqurade and you told it to chose the first option, so it did. You only told it to answer 1 to the first option. After "choice 1" sent you to Vlads, there was another choice for "Visit the Castle", "Stalk the Night" or "Skulk in the Cemetary" so it consulted choiceAdventure546 to for the answer to that question and found it's goal was set to mysticality which was not an option for Vlad, so it aborted.
