So the problem with night 4 (and possibly 5) Is that the 1-20 scale for aggression is already at 20 at the beginning of the night. I believe the game is allowing itself to go over the initial aggression, but not below it. This meaning that, even if you didn't let MalO slip by even once, the game sees it as maxed and kills the player.
This could be fixed by,
A: Lowering the difficulty (19 would be fine)
B: Allow the game to go under the initial aggression (if int aggro is 20, catching her would make it 19)
Please take this into consideration and good day person of indistinguishable gender.
