By the way Olaf, i thought I should mention I found that bug that ended your game, thanks for informing me about it, it was EXACTLY where you said it was, specifically I missed a piece of info in the JSON file that was being parsed. I'll upload the new version shortly.
Don't worry I don't expect you to slog through the whole thing again xD. The ending is simply a speech you give at the end where you can fix some of your mistakes before each culture declaring if they like you or not.
Thanks again for playing.
