I am making a mod that has the same world generation as the end basically, but I changed it a bit. When I used blocks made in minecraft(Vanilla), it would generate properly. If I use a new block(that I added), it gives me an error and crashes the game.

If anyone would like to see any more of my code, please let me know, I could use as much help as possible.
