Note: This does not ever happen with NPCS.
Sometimes when I pvp, projectiles hit me even though on my screen the projectile seems to go towards a completely different direction. Even the player who fired the projectile is facing the orientation as they should be. To prove this, I tested it with an alt.

The same thing occurs with spears and arrows as well. A player I fought threw his spear at the complete opposite direction of what he was supposed to throw towards and had the wrong orientation, yet he still hit me. It could be related to lag, but I’m not sure. Just pointing it out.
