[1.6.4]can't change id of item

[Jdb100]

Hi guys so i recently got back into modding so i set up a basic mod and started working on my mod. I was able to add a desk with a TESR but when i was trying to make the item to use with the desk i got a problem. So the problem is that what ever i set the id to it always becomes id 31999 when loading the game. I tried changing it in the config class and where you set it for the original config in the code however neither of those would change it. I did nothing different then my desk and it doesn't mention anything in the log. Here is the code for my ids and my config.

 

@EventHandler
public void preInit(FMLPreInitializationEvent event)
{
	Configuration config = new Configuration(event.getSuggestedConfigurationFile());

	config.load();

	//Ids
	deskId = config.getBlock("Desk", 675).getInt();
	journalId = config.getItem("Journal",875).getInt();

	config.save();

	desk = new BlockDesk(deskId);
	journal = new ItemJournal(journalId);
}

# Configuration file

####################
# block
####################

block {
    I:Desk=675
}


####################
# item
####################

item {
    I:Journal=31743
}

I mean, the id in the config still says 31743 (and item ids take the number and add 256 to avoid conflicts with vanilla), so it doesn't seem like anything is wrong.

i know but the config always sets the id of it to 31743 even if i change it.

Is there an item/block already occupying 875 or 1131? If not, try setting it to something above 4096.

i was able to change the id to 4756  by putting the id to 4500 in config so i am assuming i need my items to be over 4096?

okay i think i remember hearing that somewhere a while ago so thanks for the help.
