Sounds like to me(bracing for a "no shit sherlock"), that we simply need to find a way to prevent the game from going online? I mean, if it works perfectly fine when you run the activated game with the internet off, then we simply need a crack/mod that makes it so the game won't go online?
Tbh, I didn't even know Ren'Py engine could go online, and without your permission? and then change the files in the directory!? It is kinda making me paranoid about other renpy games now too lol
