Amazing work! Really like it as a developer.
Found a bug: If you add your own blocks, place them in the world, then remove them, you will not be able to join this world even if you destroyed these blocks in world, it will throw NPE in the console.
might just be improper json stuff or whatever, did you remove the block mod after leaving the world?
Yeah, I did
also, there is a way to post bugs in the discord
Ok, thank you
