Hello, I was just peacefully spending time testing out a few builds for my main YouTube series and every time I opened my inventory in creative mode I crashed.

The test on the screen when I crashed said:
The game crashed whilst unexpected error
Error: java.lang.NullPointerException: Registry Object not present: decorative_blocks:chandelier

Here is the is full crash log to help:

I don't have any Chandeliers in my world but I was told the game still has to process the item and that's why its crashing. Its only crashing the client not the server if that helps more.

Forge: 47.2.20
Version: 1.20.1
Mod Version: [ Forge 1.20.1 ] v4.1.3

You know what. Im just going to close this issue... haha, I forgot to add the mod to the server? Not sure how I managed that and how I even got onto the server.... But its there now and no issues... xD
