New bug: election/concert did not start automatically after two weeks of the single being released. I believe this may be because I released on the 18th of May, then got two events on the 1st of June(The chart and a random fight). Game froze upon loading both events at the same time, I had to close and reopen. Then the concert didn't start on the 2nd like it should have.
Besides this, I think you should allow the player to activate the election+concert themselves, rather than the game doing it automatically so this problem can't arise. Like how you can't release a single if you don't have enough money, the game should just check if 14 days have passed since the single, and THEN unlock the concert start button. I have noticed that the game starts to chug when switching into the concert/election sequences, but this is the first time it broke.
