Yea, just slept through it evidently. It happens, even IRL. I sleep with the window open, and I slept right through a major thunderstorm/windstorm that legit ripped the fence off our yard and threw it into the alleyway. Woke up next day and had to ask what the hell happened.
In game, I usually run characters with the heavy sleeper trait, never had much of a problem. But I also make it a habit to sleep in windowless rooms, after clearing the area up a bit. Precaution pays off and all.
