I was thinking someone should write a story on the premise that we are living in a simulation, where 'glitches in the matrix' like déjà vu, coincidences, freak accidents, etc., are due to accidental arrangements of people corrupting the program... but then I realised someone already had. In El ángel exterminador (1962) a group of people are trapped in a single room (level) due to their accidental seating arrangement. They are freed when they unlock the same sequence. In Groundhog Day a similar thing happens where the protagonist is trapped replaying the same level, until he figures out the correct sequence of actions to pass it. I am sure there are others.
If you want a story that handles this scenario pretty much exactly, you might want to check out “Unsong” [0] by the excellent Scott Alexander.
That world is basically a biblically-inspired computer simulation which gets corrupted when Apollo 8 crashes into the celestial sphere. Also boiling a goat in its mother’s milk causes a segfault for some reason the developer can’t quite explain.
I saw El ángel exterminador and it was great, but I don't think it hints at any simulation. The phenomenon does not really need any literal explanation, but if I had to provide one, I would rather suggest a mystical occurrence or entity such as the "angel" hinted by the title, somehow triggered by the characters, and the seating solution may be a way of telling the humans to stay in their place.
