I ran into my first game-stopping bug in Chapter 3 - Zoe is unable to enter the Rooster and Kitten after following Crow from the Journeyman Inn. The cursor changes to the appropriate "open door" icon, but click does nothing.
After the update, I have found that scene transitions seem to take a lot longer, and the dialogue is messed up - after a lag, both parties will be speaking dialogue at the same time, out of sync.
