Wow! Can you break down your numbers for each era? I'm guessing you might have 0 for one or more eras.
Yep, if I've filled in the numbers as 2, 2, 1, 1, 0, if that's correct. I just put the number of new sims that joined in completing the objectives each era. More detail below.
The two founders completed No Tech (Adele and Abbie). Adele completed the Parenting and Fishing skills, Abbie completed Charisma, Singing and Comedy.
In Low tech their first two children helped (Billie and Belle). Adele - Fitness skill, Angling Ace aspiration. Abbie - Cooking, Gardening and Flower Arranging skills, Freelance Botanist and Curator aspirations. Billie - Soulmate and Serial Romantic aspirations. Belle - Violin skill.
Mid tech child 3 of gen 2 joined in (Bronwyn). Billie - Wellness and Handiness skill, Bodybuilder aspiration. Belle - Painting and Logic skill, Painter Extraordinaire, Friend of the World, Super Parent, Fabulously Wealthy aspirations. Bronwyn - Guitar skill.
More Tech - Clara (only child of gen 3) joined in the fun. Obviously they all became Vampires right away. Billie was an elder, Belle an adult, Bronwyn and Clara young adults. They gained Fame points but didn't buy any perks. Billie - Baking and Mixology skill, Good Vampire aspiration, Culinary (chef) career. Belle - Veterinarian skill, Vampire Family aspiration, Painter (Master of the Real) and Criminal careers. Bronwyn - Vampire Lore skill, Musical genius and Master Vampire aspirations, Gardener (Botanist) career. Clara - Piano skill, Joke Star aspiration, Entertainer (comedian) career.
High Tech - all were at or close to full celebrity status when cured of Vampirism. Their ages reset to the start of their current phase and obviously the long life span helped too. Billie - Leader of the Pack aspiration, Gardener (flower arranger) career. Belle - Mansion Baron, Renaissance Sim and Celebrity aspirations, Culinary (Mixologist) career. Bronwyn - Archaeology, Selvadoradian Culture and Pipe Organ skills, Archaeology Scholar aspiration, entertainer (Musician) career. Clara - Photography and Dancing skills, Writer and Painter (Patron of the arts) careers.
I've a lot of save files so if you need any more detail I'm happy to break it down as to when they completed everything as best I can!
