running entity.remove() on a villager who has claimed a bed, or jobsite, does not reset the poi - free_tickets claimed by the villager.

Potential other POI effects may be Bells, Bee Hives, etc. where free_tickets can be reduced to 0.

Reproduction:

Create and load a simple plugin

package my.test.runs;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerInteractEntityEvent;
import org.bukkit.plugin.java.JavaPlugin;
public final class Main extends JavaPlugin implements Listener {
    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this,this);
    }
    @EventHandler
    public void onPlayerInteractEntity(PlayerInteractEntityEvent event){
        event.getRightClicked().remove();
    }
} 

Create a "Point of Interest" such as a bed(Image shows 4 beds with free_ticket of 1)

Spawn/or lead a villager to claim said bed(Image shows 4 villagers have claimed 4 beds, free_ticket = 0)

run Entity.remove() on any said villager.( Image shows removed villagers but does not set the free_ticket for poi back to 1)
