I'mma be honest, while I absolutely fucking love this VN, it REALLY shits me to see a game nearly 5 years old, and still plagued by almost game-breaking issues that's been around for at least half that time.,... I've had character routes rollback or even reset while halfway through, events jump forwards and break my saves, and even character pregnancies either reset themselves or just cause a fatal error when in previous playthroughs they worked without any hint of a problem.
All of this has me tempted to refresh myself on Python and learn how Renpy works just so I can fix the problems myself, and I just might do that, but I still can't bring myself to contribute to DarkCookie's Patreon if he's just going to ignore serious bugs like this.
