Changes to world don't pass to other clients. [1.7.10 - 10.13.1.1219]

[fhbgds14531]

I have an item that smelts blocks in world on right click, but the changes to the blocks don't get sent to other clients. If, for instance, I right click an iron ore block, it turns into an iron ingot, but other players still see an iron ore block (but the ingot is there) until they reload the chunks.

 

Here is the method that changes the block. It is called when !world.isRemote

 

 

public boolean convertBlock(int x, int y, int z, ItemStack tablet, World world, EntityPlayer player){
	Block target = world.getBlock(x, y, z);
	ItemStack smeltingResult = FurnaceRecipes.smelting().getSmeltingResult(new ItemStack(target, 1));
	if(smeltingResult == null) return false;
	if(smeltingResult.getItem() instanceof ItemBlock){
		Block block = Block.getBlockFromItem(smeltingResult.getItem());
		world.setBlock(x, y, z, block);
		world.notifyBlocksOfNeighborChange(x, y, z, block);
		return true;
	} else {
		int count = 1;
		count += Util.getLevelOfEnchantment(tablet, Enchantment.fortune);
		EntityItem ei = new EntityItem(world, x + 0.5, y + 0.5, z + 0.5, new ItemStack(smeltingResult.getItem(), count, smeltingResult.getItemDamage()));
		world.setBlockToAir(x, y, z);
		world.notifyBlocksOfNeighborChange(x, y, z, Blocks.air);
		world.spawnEntityInWorld(ei);
		count -= Util.getLevelOfEnchantment(tablet, Enchantment.unbreaking);
		if(!player.capabilities.isCreativeMode && count > 0) tablet.damageItem(count, player);

		return true;
	}
}

 

 

 

Any help is greatly appreciated!
