[2021] Spears Should De-Spawn With Zombies

They should or shouldn’t? Anyway, what’s supposed to happen is if the body disappears, any projectiles stuck in it are put in one of those little cloth sacks for one more chance to retrieve it, before the sack disappears too. Generally, things that aren’t blocks will de-spawn sooner or later, as a form of garbage collection. For the sake of long-term performance, the game world is designed to not get cluttered with more and more stuff.
