On PC, saves are kept between versions if you play on the same computer. On Android too if you upgrade the app. Though with the last update, there was a major change on Android which might have been the cause of you losing your saves.
If I open the V6.2 I have all my saves, if I open V7.5 it seems I've lost every save, I'm on Pc, same Pc :(
Ok, odd. You can try to manually transfer saves. When you open Eternum's folder, your saves should be in the "/game/saves" directory.
Thank you so much! Now it works with all the saves done! Interesting plot, thank you for your content!
Glad to help, but I'm not the dev :P
I know I know you're not! But you've done a nice plugin to the games from the devs! So thank you too, at least for the interest!!
