artist, Themba and Khenbish (no robert no wolf), I did get pool and bar but i didn't get the gym finished or even translate Argos's diary (this is my second play-through I stopped trying to optimize this after that). and if we trust the options on the survey then the ranks after grootslang will be: tapir hydra bull, it would make sense for these to be implemented even if we cant get the number to be high enough to reach them in this build.
let me guess you did the asterion project instead of taking Robert. I took Robert and did all the projects (except the swimming pool and its bar but I checked I can build them) and find the bell that unlocks the black/white coat. anyway I know that at the next construction I could finish them. The important thing for me is that asterion is happy but a bit submissive and a good pedro/oscar relationship.
