So, due to a typo in version 1 of my mod, a block was registered as ModName:Block.name, In version 2 this was changed to ModName:Block

Updating to version 2 would remove the block from any worlds. Is there any way to make the name change, but make sure the block stays in the world?

 

Thanks-

The unlocalized name has nothing to do with how your block is stored, it is merely a display thing. Changing the unlocalized name does not "remove your block from any world".

My bad, Not the unlocalized name, but the name used when calling GameRegistry.registerBlock();

I thought they were the same for a moment there.

I don't really see the name to change it. But if you must, you can use

FMLMissingMappingsEvent

to remap the missing block to the new version.

Thanks, That seems to be working.
