I've completed the Haven questline recently, and to be honest it was rather frustating. Most obvious downers were some bugs - i couldnt figure out the whole sprinklers thing and the game acted like i both had and had not any lighters and fuel, using the wrench on the pipes threw error screen every time.
And then gameplay issues where Sammy got raped during haven as a virigin and started what i can only descibe as a crash spiral. Pretty realistic i suppose, but not very fun when im forced to watch sammy down 3 beers in a row (still at 0 mood), pass out from alcohol abuse, go to the guy to get more beer, pass out from lack of sleep, proceed to down all her beers again etc until a mood debuff expired. Trough it all i could only do single steps before the game would take control away from me again to make sammy drink, whore for more beer or pass out. The debuffs from the rape and the alcohol abuse basically locked both rest and mood at 0, leaving me unable to act.
In the end i just collected 10 rumours by eavesdropping and walked out of the place, which im pretty sure is the most boring way to complete the mission.
