[1.16.4] IWorldReader.getBiome() - what's up with the Biome reference I get?

[OreCruncher]

Forge 35.1.10 if it makes a difference...

 

I have client side logic (on the main client thread) that scans around the player surveying the biome distribution.  In single player, the Biome reference I receive returns back a non-null value for getRegistryKey().  However, when I connect to a remote server, the Biome reference I get back from the getBiome() call returns null for the getRegistryKey() call.  Ultimately what I am trying to accomplish is correlating the Biome reference I get back from getBiome() to an entry in ForgeRegistries.BIOMES.

 

EDIT:  Found it.  I recalled that F3 debug shows the biome ResourceLocation so I went to see how they did it.  Essentially the Biome reference would be used to look up in the DynamicRegistry to get a key, and then that key could be used to look in the Forge registry:

 

final ResourceLocation loc = world.func_241828_r().getRegistry(Registry.BIOME_KEY).getKey(world.getBiome(pos));
return ForgeRegistries.BIOMES.getValue(loc);

Should both return the same object.

So your code is equivalent to Math.sqrt(x*x).

 I agree it should, but for some reason it looks like it isn't.  Not sure why.  This is my first time dealing with Biomes in 1.16.4 so I could be doing something boneheaded.  To be clear this only happens when connecting to a remote server.  If I run single player with integrated it doesn't happen.
