the game should save, it saves for me after each turn it saves.
On each turn your expedition (scouts) automatically venture out depending on their upgrade level and return with a chance of finding Seeds, research, and spare parts.
In my side I tried exiting and hitting play again, and it started at the beginning. It may be an issue on my side, or may be I did something wrong. In any case, I'll keep an eye on the game for the future :D.
About the update, I didn't mean it as an attack, just as a heads up. I'm happy it's all good!
it shouldn't effect it but I will jot down to test the portable specific files, btw I would suggest the installer version anyway its just a nicer experience to be able to launch the game from the program files area, also at a much later time I hope, you can quiet easily uninstall the game via the uninstall programs system in Windows which means you don't have to remember which folder you put it in.
This feedback is very useful as I would like to get to the root of your issue.
can I suggest you play the installer version and then let me know if it still doesn't save, just delete the folder Hope in the folder Digital Gamez the path I posted earlier, then run the installer version up until turn 3 then exit via the exit button and quit the game from the main menu, then boot it back up and check. Please reply your findings 🙂👍
