Solved Set a block "Correctly" in the world

Oke i have the following problem. I would like to replace certain blocks with a chest containing the block that has been replaced. The block itself loads the chunks so i can easily track them. The function itself is working but i get this error.

Code:

15:04:52 [SEVERE] Block at -129,64,189 is CHEST but has buildcraft.factory.TileQuarry@ee6b99e. Bukkit will attempt to fix this, but there may be additional damage that we cannot recover.

This is the code i am using:

Code:java

for (World w : getServer().getWorlds()){
                    getLogger().info("Checking " + w.getName());
                    for (Chunk c : w.getLoadedChunks()){
                        for (int x = 0; x < 16; x++){
                            for(int y = 0; y < c.getWorld().getMaxHeight(); y++)
                            {
                                    for(int z = 0; z < 16; z++)
                                    {
                                        Block block = c.getBlock(x, y, z);
 
                                        if (block.getTypeId() == 153){
                                            getLogger().info("Quarry found on " + block.getX() + " " + block.getY() + " " + block.getZ());
 
                                            block.setType(Material.CHEST);
                                            block.setData((byte) 0);
 
                                            Chest chest = (Chest) block.getState();
 
                                            chest.getInventory().addItem(new ItemStack(153,1));
 
                                            return true;
 
                                        }
                                    }
                            }
                        }
                    }

I know this is possible because i have seen coreprotect replacing these blocks without an error.

Nvm i found that calling "block.breakNaturally(new ItemStack(0,0));" Breaks and cleans the block location correctly so you can correctly set them. Sorry for posting this . But maby it could be helpfull for other people
