Trivia

 * During the event there was a cap how much you can earn with project from the Project Board. It was set at 4,500 every day, with the last days 9,000. This was only for the blueprints earned with projects, not the bonus every day or other actions that earned blue prints. Once you earned all the prizes the cap was lifted.
