Sometimes when I'm fighting pirates (code 185) they randomly glitch but its really rare where they spawn like they are just about to hit the floor after dieing. When they do this they don't appear to follow you So it looks like they are attacking you from afar. I asked my friend if he could also see it and he said no so its only the person attacking the pirate.not sure if this happens with Every monster but it definitely happens with pirates
