--- Comment #107 from ruawhitepaw@gmail.com ruawhitepaw@gmail.com --- I can confirm that the fix above works for me. I had a save where I was one turn away from completing Astronomy (my first Renaissance era technology) and it would crash each time my next turn started. Copying over the XML files has fixed it and I got into the Renaissance, with my first spy :).
So this fix should work on existing saves, too. At least it did for me.
