Thanks for the report. I believe the issue you encountered is a crash related to the update. While you can find details in the development policy, I prioritize development speed over backward compatibility. Considering we've only been at TDC for two and a half months and have already reached this stage, I hope you can understand. I apologize, but please clear your browser's local storage and reset the game. As compensation, I've included options to start the game from middle points. Please read the FAQ and the development policy article.
