I always have an issue with updates where either the game freezes when Aura's "real world" avatar is supposed to appear and I get error messages about missing image files. I would just rename other images to the missing image so that the cutscene would play. With the .42 update, I don't even get the error message anymore and the cutscenes just freeze. My guess is that its a save file thing, but that would not explain why the files were reported missing.

I am having a similar issue with the game "Lust Doll" could you explain how you just renamed other images? Did you literally just pick a couple images present in the game and just change their name?

The error message that I got told me the missing file name and location, so I would just choose a similar named file in the folder and make it match the missing file name.
