[1.11.2] [SOLVED] addSubstitutionAlias

Hello.

For some months I encounter a bug preventing me from using GameRegistry.addSubstitutionAlias. Since I saw at least some people on this forum got it working, I'm posting hoping to get some help.

I always substitute things at the Register<Block> event.

What I do for my Blocks is 

GameRegistry.addSubstitutionAlias(oldBlock.getRegistryName().toString(), GameRegistry.Type.BLOCK, newBlock.setRegistryName(oldBlock.getRegistryName().getResourcePath()).setUnlocalizedName(oldBlock.getUnlocalizedName().split("\\.")[1]));

Crash log : https://pastebin.com/riFX21WF 

I'm not sure what could be wrong.

EDIT : Problem solved. As I was not using the Item object for anything other than the substitution I did not hold it in a static reference, instead creating it directly when passing the parameters of addSubstitution. This probably resulted in two separate instances for each thread and funky times.
