I don't think they're complaining because of the bugs. Games can have bugs, but this one is going the way of Duke Nukem Forever: In development hell for years, loads of money thrown at it, and it's probably not gonna turn out that great...
There's other games out there with peanuts for funding and they've got less bugs and better gameplay overall from day 1. Plus, it doesn't help the head guy on this project is kinda universally hated (he has a reputation for not doing projects, fighting with his team and pissing off strangers online. True or not, it's a factor towards how people treat him). And the updates are pretty slow too, or just not impressive for the thousands it's apparently being funded. Or that bugs aren't fixed despite constant complaints about them. Or that the porn isn't really that interesting...
I mean, take your pick, kid. People shit on this game for more reasons than the bugs, some reasons better than others. Even I can't stand it and I'm normally gung-ho about porn games (and, admittedly, do find the head guy's fursona a little hot). It's just not a great game, bugs or not. :/
