Not sure if anyone else has experienced this in 0.3b, but the cell phone message interactions are a bit broken. When you send texts with the girls, once the text messages have gotten to the bottom of the phone screen, any new messages don't auto-scroll, so you cannot see their responses.
If you close the phone and go back in, you can see them. Scrolling up and down in the message history is a bit spotty, where sometimes it works and sometimes it doesn't.
I did not see this issue with the previous 0.2 build, so I wasn't sure if this was something on my end, or was related to the UI changes/tweaks.
I started a new game from the beginning as the OP noted that the saves from 0.2 were not compatible with 0.3b.
Aside from this small issue, everything else seemed to work just fine. The new UI changes are appreciated and the story is really great so far.
