once i clicked a mini-upgrade, when i came back after two hours, the money i spent for the mini upgrade was gone, but there was no mini-upgrade so i had to click it again. i had to repeat it at least three times before it worked, each time subtracting crystals, why?

Once I was in a Rio CTF, then i was just randomly driving along one of the streets, when I self-destructed. WHAT IS WRONG WITH THIS?!
