There are no advantages at all, purely sports interest, so to speak, and achievement as it is written))))

I drove 27 settlers, 20 stores and it reached 96%, and then the green arrow, then the red - does not go higher. These guide writers would have posted a 99% save so that people would not suffer.
Yes, and according to the guide - do not leave the village, then leave. The most idiotic latest achievement remains.

Who needs my preservation with 99% happiness. Wait a little and it will be 100%. the achievement is valid.

Build 20 clinics and bars (all of the third level) and that's it. What is the problem? I built it like that, stuffed 20 settlers there, supplied them with food from a neighboring settlement, and left to go about my business. Achievement was given when I was on a mission in Boston.

That's just the point - for some reason resisted and did not go further. Rearranged the shops - and then it went. Maybe there was a bug.
