Subject: [PATCH] Refresh ProjectileSource for projectiles
|
|
|
|
Makes sure the value returned by Projectile#getShooter in
|
|
the API matches the owner UUID specified in the entity nbt.
|
|
Previously, after the entity reloaded, Projectile#getShooter
|
|
would return null, while the entity still had an owner.
|
|
|
|
Also fixes setting the shooter/owner to null actually
|
|
clearing the owner.
