Owen said: Yes, this broke my random new world saves for my current game. Is there any way to revert to 1.29.5 or similar? The latest version available to revert to on Steam is 1.28.3. Click to expand...

Did you actually try to load your RNW saves? I tried it after clicking OK in the warning dialog and it seemed to work and achievements were still enabled. But that save was made on the first day without doing any changes to the country. But two people on reddit were also able to load their RNW saves successfully.Before you try it you should make a backup of your save game just in case that there are any problems.
