Hello playing on a server and my friend threw a coral spear into my claimed area he lost it/ never returned it to him although it had built-in loyalty. Is there a way to prevent this, or is there a configuration to allow these projectiles to be thrown into claimed areas?

Error in chat says "This projectile of yours is not allowed to land on blocks in this chunk!"

The server owner needs to add the projectile entity of the coral spear to the block access exceptions the way regular tridents and arrows are by default.
