Well, the patch has never been useful to be honest. We knew from day 1 that the patch existed that it wouldn't be. We knew her bio dad would eventually turn up, and now that we know more details it's clear why a patch doesn't work for this game.
All the incest purists just need to quit crying and move on if they can't play games that don't include actual incest (involving MC). I love incest in games as much as then next guy, but it's not a must have for me, it's not no damn deal breaker. Not every game needs to have incest, and the people who cry when there's not incest need to grow up and stop being entitled.
