[1.7.2] ItemBlock in GameData.itemRegistry isn't remapped

[Brad16840]

My mod is working fine in worlds created in 1.7.2 but I'm encountering problems with Block objects in worlds imported from 1.6.4.

The problems seem to be caused by GameData.injectWorldIDMap remapping my block ids in GameData.blockRegistry but not remapping their ItemBlock counterparts in GameData.itemRegistry

 

[server thread/INFO]: Found block id mismatch balancedexchange:reactivity_block : 167 501

 

Block.getBlockById(501) == BalancedExchange.reactivityBlock

Item.getItemById(501) == null

Item.getItemById(167) == new ItemStack(BalancedExchange.reactivityBlock).getItem()

Item.getItemFromBlock(BalancedExchange.reactivityBlock) == null

Block.getBlockFromItem(new ItemStack(BalancedExchange.reactivityBlock).getItem()) == Blocks.air

 

Changing my block's id to 167 in 1.6.4 fixes the problems but obviously isn't a valid solution.

 

I'm using latest versions of forge (1.7.2-10.12.0.1034 and 1.6.4-9.11.1.965) and in 1.6.4 I register the block in BalancedExchange.preInit using GameRegistry.registerBlock(reactivityBlock, "balancedexchange:reactivity_block")

 

Is this a bug with injectWorldIDMap, or is there something I'm missing?

It looks like there is a ticket open for this on Github.  I ran into this today working on a test server for forge 1033.
