как перемещать ItemStack в конкретный инвентарь?

[Talloran]

у меня есть методы:

@Nullable
    private static Inventory getInventoryAt(World world, double x, double y, double z) {
        List<Entity> list;
        BlockEntity blockEntity;
        Inventory inventory = null;
        BlockPos blockPos = BlockPos.ofFloored(x, y, z);
        BlockState blockState = world.getBlockState(blockPos);
        Block block = blockState.getBlock();
        if (block instanceof InventoryProvider) {
            inventory = ((InventoryProvider)((Object)block)).getInventory(blockState, world, blockPos);
        } else if (blockState.hasBlockEntity() && (blockEntity = world.getBlockEntity(blockPos)) instanceof Inventory && (inventory = (Inventory)((Object)blockEntity)) instanceof ChestBlockEntity && block instanceof ChestBlock) {
            inventory = ChestBlock.getInventory((ChestBlock)block, blockState, world, blockPos, true);
        }
        if (inventory == null && !(list = world.getOtherEntities(null, new Box(x - 0.5, y - 0.5, z - 0.5, x + 0.5, y + 0.5, z + 0.5), EntityPredicates.VALID_INVENTORIES)).isEmpty()) {
            inventory = (Inventory)((Object)list.get(world.random.nextInt(list.size())));
        }
        return inventory;
    }

    public void Insert(ItemStack itemStack, World world, BlockPos pos){
        Inventory inventory1 = getInventoryAt(world, pos);
        Autosorter.LOGGER.info("инвентарь: " + inventory1);

        if (inventory1 != null){
            for (int e = 0; e < inventory1.size(); ++e){
                if(inventory1.getStack(e).isEmpty()){
                    ThisPlayerEntity.equipStack(EquipmentSlot.MAINHAND, ItemStack.EMPTY);
                    inventory1.setStack(e, itemStack);
                    Autosorter.LOGGER.info("стак (" + itemStack + ") сложен в слот №" + e);
                    break;
                }
            }
            inventory1.markDirty();
        }
    }

но в инвентаре(сундуке) который нашёл метод getInventoryAt ничего не появляется,
