First let me start by thanking you for your diligent work. Such detailed observations made it easy for me to fix the first 3 issues. The new version is available to download already, both on itch and Patreon.
For point 4, I'll need to investigate much more. It might be an underlying problem with the version of Narrat used and upgrading to the most recent of Narrat is not in the plans right (it would require weeks if not months of work do to many breaking changes and customization that needed to be built into Narrat, time currently spent on Ascension II).
As for point 5, what I could do is provide a semi-manual way for players to make saves at Edgar's apartment / cabin. I originally opted not to do that, as I wanted the game to be less of a scrub save type of game, but if the players want it, I can put a few hours in implementing it.
Lastly, are you on my Patreon? If yes, please send me a direct message, there's a possibility I'd like to discuss with you.
