The only build of this game on GOG was uploaded on 2023-11-14, according to gogdb.org. The Steam version of this game got two new releases with important bug fixes (Saving and Font Hotfix on 2023-11-17 and Hotfix 2 on 2023-11-22), but neither has been released on GOG yet as of 2023-11-26.

I would rather buy the GOG version of this than the Steam version, but I don’t want to risk playing the version with the save-erasing bug. Can you please update the GOG version?

We did get a new patch recently

But since there were no patch notes I have no idea what was fixed. Probably these hotfixes since I did not see a new patch on Steam
