I'll continue looking into this, though I'm a bit constrained by how fragile the Android installer is with respect to external storage.
Props to Google for developing Android, but I do wish they'd make it a bit more robust...
I'll check the HIB page for new builds (if you see a reason to make them in the upcoming days) and give feedback.
There's actually a good reason for this, which is that the Android save files are not backward-compatible -- if you load an Android save in one of the PC versions, the game itself will load but you'll lose your current inventory and all visited data on the world map. I didn't want to give the impression that the files are interchangeable by using the same filename extension.
So, you can use PC saves on Android, but you won't be able to use them on the PC. Duly noted.

That's interesting, because the android version is able to retain all the information. On a related note, is this a bug on the PC builds?
This may be another side effect of the external storage problem you reported earlier. Again, my suggestion would be a factory reset.
Indeed, I'll try to do that.
