If you write the (dummy) code of what has to be added to JigsawPattern, I can write the corresponding coremod

Or can this even be done via access transformers or reflection?

I think its possible with access transformers. Don't know why i never thought about it. I will test it later

@Cheaterpaul 1.14 is currently missing the hunter trainer house and the village church, right?
What exactly do we need to add them back. I guess the Forge PR won't be accepted any time soon. So what can we do without? If we need some small modifications in MC code we could use a coremod

basically we just need a method in JigsawPattern to add Jigsawpieces to the pattern

This is all done right?

Could keep this open to track Forge PR MinecraftForge/MinecraftForge#6378
