I give up this game.
I pass the game according to walkthrough, and after the task at Sophie (NTR or Neutral, Alvin sex with Prostitute or Sophie) When I got a bug and flew at the end of the task instead of what I had to give a bottle of perfume to Sophie, instead I only had thanks from Kristel and Sophie, I couldn't do anything more.
Now, when I need to gather a group of guys to enlarge a new house (family relocation), when I want to gather Alvin to help me, he is still angry with me and is still sitting in his room.
This game is full of bugs, it's annoying. It is a pity, because I wanted to finish part 3, there is not much left, but I cannot go further through this mistake.
