Hello, I wanted to add my custom village to my dimension, but it crashes when I enter my dimension

My code is on my Github

The crash report:

Seems pretty obvious to me, go look at

MapGenStructureIO

, you have to register your component.

A thanks, found that the registerVillagePieces method wasn't called
