What is the weirdest glitch you've seen while playing the game?

I remember playing the game normally when I used the Bad Romance Easter egg (aka the JoJo stand one).

Suddenly, as I was punching a crowd of students, one of the corpses (either Roko or Shozo—I don’t remember which one :( ) was so laggy and deformed but started walking off like nothing had happened. When I got closer and hit it, the game crashed lol
