So I just finished Uta's route, i have the achievements for the routes I started and completed, and even her started route achieve, but not the finish one that I just did. I even verified the files twice and it said it was good, lost all of my progress though. And still after going through it again no achievement... wtf steam? Anyone else experiencing this?...

Is there a patch for this version or do you have to buy it from JAST?

The patch from the the NekoNyan website is getting flagged by McAffe as a virus. I did think it was weird that it downloaded as a zip file and was almost two giga bytes as opposed to the other patches that downloaded as 7zip files and a relatively small.

I'm not looking for any spoilers, just wondering how to go down Kotohina's route? I've tried writing her name in the notebook every chance I got, but it always leads me to the short ending with Masora. Is her route only unlocked after finishing everyone else's route or is this a bug?...
