When using SADIST and scrolling through weapons not fast enough, replay of that race thinks the bomb was activated and starts fusing the car. The car in the replay can even pass that bomb to another car and that car explodes on video, although not in reality. Not a dealbreaker glitch, but something I noticed when fooling around with sadist + clockwork + drinkme and rewatching the replay.
Almost the same thing happened to me, when i was playing RVGL and finishing the Bronze Cup since i was bored i noticed that the bomb didn't want to go on the car and instead it was keepable. The only thing to make the bomb go on the car is to (on android) clicking on the bomb. The issue was that for the AI's the bomb stayed for them forever. When i restarted the game it was back to normal again like nothing happened.
