The update is bugged. Please fix this as soon as possible! I tried to load day 3 when Bjorn's route ended last update and it showed me this screen. It doesn't let me and it shows this 'an exception has occurred.'
I'll look into it now, but sometimes RenPy decides for some reason to break some saves ;_; if rollback/ignore doesn't help, it's possible that you'll have to start from Jump to route and use skip functionality to get to the point you were (there's an option to enable Skip Unseen in preferences!)
Unfortunately sometimes Renpy just nukes saves. At least this one still exists. Mine for both Dawn Chorus and The Smokeroom got obliterated by the new updates.
