There is an event on mansion's MC room sometimes which honestly is very weird - when you go to sleep and the monster/whatever it is bumps into the window then appears inside the room and, I don't know, screws up MC hand or something.
The event itself isn't the problem, but it stacks with other nocturnal events in a way it becomes really weird. For example, I had this once and, right in the middle of it, it also triggered pixie+chloe event, and after it finishes, the monster event resumes with MC waking up in the morning talking about the aftermath; in another occasion, I had this and, again, triggered emma event where you meet her on the park at night, then the aftermath of monster event at the morning.
It gives that impression where you take a shot, but your doorbell rings, you grab the pizza, pay the guy, then go back inside your house and dies from the bullet wound.
Probably the event should suppress other triggers until it was finished or something, I don't know. I don't feel like this is intentional.
