Sul sul fellow simmers! The Miller Legacy is my first Legacy Challenge and the way I found to explore the (for me) new The Sims 4 game in the moment I decided to buy it. It's the translation...
Yup, I tried to read all the weird events happening in Strangerville with a slightly different key than the one proposed in game, so the infected sims become "contaminated by the neurotoxin", the vaccine becomes the antidote, (at least for now) the Mother plant is just "the huge and scary plant" and so on. Who knows whether I decided to keep this different interpretation all along, or if I eventually converged with the canonical storyline... :P And Erwin is definitively very shady too... But he mostly remains weird, so weird XD
