Haha thanks for playing ☺️
The stability is a discipline from the original, and rebooting is supposed to increase if triggered during the call. If there's no call and reboot is triggered the stability is supposed to be deducted -10. And if missed call -1. I didn't test all the scenarios with different modes and paces, might be still some bugs 😬
I am happy to know that you figured everything else though 😅
The music is this track (used it in deployed game as well):
