I tried to get this stupid trophy (worst trophy in all Fallouts i've played imo) legitimately but my god this was a waste of time. After spending few days on reading guides about it game fucked me in the ass. I was stuck at 85 happiness in Sanctuary Hills. My happiness jumped from 85 to 84, again to 85 and again to 84. Like wtf? Then i decided for a new start in Vault 88 just to relive the nightmare. This time i got stucked at 92-94 happiness. My favourite part is when your Pip-Boy shows you you have 0 food, 0 beds and 0 defence in your settlement after you put your heart in it's developement. I nearly lost it becasue of this trophy and i must say i'm pretty impressed that over 60000 people from this site got it. Either way I had enough of typical Bethesda buggy bullshit. I spent nearly 90 hours with Fallout 4 and decided to use 5 cages glitch. Worked like a dream. Got the trophy in less than 5 minutes. I wanted to thank all Fallout 4 community for finding this exploit. At least it was working instead than broken happiness system invented by Bethesda in Fallout 4.
