Cool, I'll look into those.
I think it might be possible to fill the bar without the earring, by the way, if you make exactly the right choices but it would be much more difficult. But that's clearly a bug so I'll fix it when I've finished implementing new features for the next release.
I don't know if I'll have time to upgrade the save system before the next release as that's quite a big feature, but I do plan to have a save option beyond the 'automatic' one in the future.
