                Collections.sort(itemEntries,
                    new Comparator<Map.Entry<Integer, InventoryItem>>() {
                        public int compare(Map.Entry<Integer, InventoryItem> i, Map.Entry<Integer, InventoryItem> j) {
                            return (i.getKey().equals(j.getKey()) ? 0 : (i.getKey() > j.getKey() ? 1 : -1));
                do {
                    Map.Entry<Integer, InventoryItem> i = itemEntries.get(0);
                    remove(i.getValue());
                    deathDrop.add(i.getValue());
                    itemEntries.remove(i);
