There seems to be no change in the Lily route from C to D. I tried starting from the end of C to starting all over and still no change. So, were there only cosmetic changes? Because the story doesn't seem to have extended at all. I hope she wears even shorter school skirts or goes without panties or better yet, both.
Unless I'm missing something, this update wasn't an update at all.
After the above, I decided to install the patch and as with other players after the purchase of the bikini, in the morning I am locked out of going anywhere. Stuck in the bedroom. How ironic, the bugfix, bugged everything.
