If it's any consolation, the duel is actually irelevant to the final outcome. If it doesn't get used, or doesn't proc because day ends, a Magic mislynch puts the game at 4/2/1 going into Night 9. Then, because town have nothing to stop a kill, th mafia kill will go through and put the game to 3/2/1 going into Day 10. At this point, the town can't lynch without Prof voting with thm, when not only does that run the risk of him being shot by scum in retaliation, it also is to his wincons benefit to delay the game. So no lynch occurs Dy 10, scum kill again and the game is won.
Effectively, the game was over the moment Magic was mislynched, even if you remove the duel entirely.
