I bought LuAnn and the Cracker Factory after the Helen Lovejoy quest (level 50). I completed all steps of The Investorettes, Money and Milhouse, and Helen Lovejoy's stuff. On the wiki, it says that part 1 of the The Investorettes unlocks the Fleet A Pita and requires it be bought and placed. I completed all related quests and the Fleet A Pita never unlocked in Springfield or Krustyland.
It could have something to do with the fact that I have Bumblebee Man, since The Investorettes quest was different than it is described on the wiki. My quest ended with them planning a Luchador wrestling match.
How do I trigger the Investorettes quest that will allow me to get the Fleet A Pitas?
