I think people who only rely on save-states can blame themselves for the trouble. If you took at least a few minutes of your life reading on about save-states you should know they can be unreliable and can't be used bullet proof.
I never ever use them. I always save with the in-game method. I don't trust save-states. Why is that such a hazzle for so many people all of a sudden? It gives a bullet proof method of saving your games instead of relying on itchy save-states.
I think it should be stated in the readme instead that save-states are not to be trusted and to use in-game saves. The dev shouldn't have to take the blame for other peoples stupidity and lazyness.
