how do I download the new updates without having to restart
Unfortunately, because I reworked the UI and added accessibility for the visually impaired, some saves no longer work, but some do.
Because of this fact, I made an "Episode Skipper" you can toggle on in the options menu to skip to the most recent content quickly, either via a pre-defined save, or craft your own via choices. It's the best I can do.
I'm sorry
