I haven't played it yet but I opened it, loaded my last save and noticed the new sleep feature so tried it and after waking up I got 'Image Prinny A' not found in the top left.
Also the old saves don't have the new content. It seems you have to start a new game to get the Chapter 2 stuff which isn't so bad because it's probably good to have a refresh on the story before continuing and it doesn't take long to get there again if you skip the dialogue but still weird. I'll probably wait until we get 2.1 before playing it because there's probably gonna be a good amount of bugs.
I'm looking forward to it though, chapter 1 was very good and I liked all the different options and routes.
