Fireworks factory

I’ve had a slight glitch in two of my games with this. I collect Bart when he finishes, but there is no animation, no final dialog. The task icon for it is grayed out and tapping on it does nothing. In each game I stored it, synced, returned but nothing changed. Even though the task is no longer yellow-highlighted I sent Bart back to the Fireworks factory to do it again and when completed this time the task finalized in each game. Whew
