Hrmmm.... Obviously I don't know what the dev plans for the next release in terms of loading saves, so I can't say for sure. In the past, though, I've been able to save on screens without "save here" and had my saves load w/o any issues. (I did not bother to save on a "save here" screen in v0.6, and loading my save for 0.7 worked just fine.) I would assume, unless someone says otherwise in the future, loading almost any save should work. Maybe back up a few images and save again, just to be safe; since it's so close to the end, I just saved at the last Alex-Hannah choice (at the party).
