There seems to be a very strange bug in this game where infected people will refuse to isolate, leading to their infecting others.
That's obviously a bug because nobody is that stupid in real life. It's not intentional. It's a bug. Nobody does this. It's a BUG. NOBODY DOES THIS, DAMMIT! IT'S ABSOLUTELY 100% A BUG AND NEVER HAS HAPPENED OR WILL HAPPEN EVER!
This game makes me unreasonably misanthropic.
