Solved how could I prevent autostacking?

Hello,

so I got a little trouble and I also probably know what is causing it but I need to know how to stop auto stacking so it would not change the Item entity object.

for now I do something like this, and I know this is also the reason why you shouldn't store objects like this way:

Code:

@EventHandler
    public void onBleed(EntityDamageEvent e) {
        LinkedHashMap<Location, Item> hash = new LinkedHashMap<Location, Item>();
        for(int i = 0; i < e.getDamage()*3; i++) {
            Location loc = e.getEntity().getLocation();
            loc.setX(loc.getX()-(range/2));
            loc.setY(loc.getY()-(range/2));
            loc.setZ(loc.getZ()-(range/2));
            int x = rand.nextInt(range);
            int z = rand.nextInt(range);
            Location newloc = loc.add(x, 5, z);
            Item item = newloc.getWorld().dropItemNaturally(newloc, new ItemStack(Material.WOOL, 64, DyeColor.RED.getWoolData()));
            item.setMetadata("bleed", new FixedMetadataValue(xEssentials.getPlugin(), UUID.randomUUID()));
       
            Location loca = newloc.getWorld().getHighestBlockAt(newloc).getRelative(BlockFace.DOWN).getLocation();
            for(Entity entity : e.getEntity().getNearbyEntities(14, 120, 14)) {
                if(entity instanceof Player) {
                    Player p = (Player) entity;
                    p.sendBlockChange(loca, Material.WOOL, DyeColor.RED.getWoolData());
                }
            }
            hash.put(loca, item);
        }
        BleedRegen regen = new BleedRegen(hash);
        regen.startRegen();
    }

but since it autostacks, the value in the LinkedHashMap does not work with Item.remove(); because the object has been changed to something else probably due the autostacking.

how would I go about to stop this?

thanks

-edit-

got it working, I just mentoided for some reason it does delete the ones in the LinkedHashMap but there are doubled/cloned stacks so to fix that I just looped through entities in the world and checked the custom metadata and from there removing the item that worked fine
