^^ Not sure modding is officially sanctioned, enabled, or supported by the devs. I think they said 'after release' on that. Anyone can hack a game, as long as it does not proactively defend itself (eg validate all game files against an encryption hash / crc etc and fail if any are not matched) from it, and not adding checks for defending against hackery isn't explicit sanctioning (though sort of a nod and smile in that direction). Most MMOs and such actively attempt to defeat modding/cheating. Most solo games don't. The in-between (usually co-op) games like this one.. are what they are.

And I strongly disagree that restoring a backup after a crash is cheating. This is why backups exist. Is it still cheating if the current file won't load or is totally gone? That seems extra weird to call out. Granted you CAN certainly abuse backup files to cheat (this is my preferred approach if I feel the need to cheat). That is not what the backup files were intended for.
