Non Persistent Wither Skulls
by azyrod
Non Persistent Wither Skulls stops wither skulls from lingering in unloaded chunks, so a skull disappears instead of flying on indefinitely.
What it does
Wither skulls normally keep flying after they are launched, even when the chunk they are in is not loaded, and some can drift around a world for a long time. This mod removes a skull once it leaves the loaded area, so a skull cannot reach a distant unloaded chunk and carry on as a stray projectile. Combat skulls keep their behavior while the player is nearby, so a fight with a wither still works as intended.
Installation needs only Fabric. Only the server needs it, and players join without installing anything. Non Persistent Wither Skulls is open source under the Apache License 2.0 and is published for Fabric across seven release versions, 1.21.10 – 26.3, with 1.0.3-mc-26.3 as the latest file for 26.3.
Key features
Unloaded skull removal
Wither skulls that enter unloaded chunks are removed, so they cannot persist in the world as permanent flying projectiles.
Combat skulls kept in place
Skulls fired during a boss fight stay active while the player is in range, so the encounter plays out as the game designed it.
Stray skull cleanup
Skulls that would otherwise drift for long periods and cause random explosions in a world are cleared out automatically.
Server-side operation
The change happens on the server, so clients need nothing extra and existing players can keep playing unchanged.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Clearing stray skulls
A world shows explosions from old skulls flying far from any player. Removing skulls left in unloaded chunks stops those blasts.
Staged skull pranks
A builder who wants to recreate the Hermitcraft wither skull prank can hold skulls in place for the full sequence, since the mod keeps them active while the player is nearby.
Who it’s for: Server owners who run survival worlds and want wither skulls to stop once they leave the area a player is in, and map makers who stage wither skull scenes.

What the author says
This means that if a Wither shoots upwards, and the skull doesn't hit anything, it will fly up eternally. This is usually not a concern for lag or anything, since you usually only have a couple of such skulls flying in the air, but you also don't really have a way to clean them up. They can also just fly almost…
